    If the SQL query doesn't run, output this error message:

    if (!$outcomes) $e = mysql_error($connection); reecho "Error in running SQL remark.".$e;

    Use the mysql_num_rows() characteristic to achieve the variety of rows in the result aid:


    If the number of rows is improved than 0, create an HTML desk to screen the consequence records. Iterate over the influence set using the mysql_fetch_array() formulation to attain a row of statistics. To achieve an associative array for each and every row, set the result_type parameter to MYSQL_ASSOC:

    while ($row = mysql_fetch_array ($effect, MYSQL_ASSOC))

    Output the row data to an HTML desk the usage of associative dereferencing. for example, the Journal column price is got with $row['Journal']. The retrieveMySQLData.personal home page script retrieves information from the MySQL database (record 2).

    Run the personal home page script in Apache2 server with this URL: http://localhost/retrieveMySQLData.php. HTML information will look with statistics bought from the MySQL database (figure 2).

    MySQL 5.0: To plug or no longer to plug? | true Questions and Pass4sure dumps

    Open supply database dealer MySQL AB has released the most up-to-date edition of its signature database administration device, MySQL 5.0, with fresh pluggable storage engines -- swappable accessories that tender the potential so as to add or glean rid of storage engines from a are animated MySQL server. talked to site professional Mike Hillyer to learn the pass MySQL purchasers can edge from the brand fresh pluggable storage engines.

    Hillyer, the webmaster of, a celebrated site for individuals who sprint MySQL on desirable of windows, currently holds a MySQL knowledgeable Certification and is a MySQL professional at

    What exactly execute pluggable storage engines deliver to MySQL that wasn't obtainable in obsolete types?

    Mike Hillyer: Pluggable storage engines bring the ability to add and remove storage engines to a working MySQL server. ahead of the introduction of the pluggable storage engine architecture, users had been required to cease and reconfigure the server when adding and disposing of storage engines. the usage of third-party or in-condo storage engines required additional effort.

    if you had been chatting with a database administrator (DBA) now not established with MySQL, how would you narrate the value of the brand fresh pluggable storage engines?

    Hillyer: Many database management programs disburse a 'one-measurement-matches-all' approach for information storage -- everyone table facts is handled the equal manner, in spite of what the records is or the pass it is accessed. MySQL took a special approach early on and carried out the thought of storage engines: diverse storage subsystems which are really expert to distinctive disburse instances.

    MyISAM tables are impeccable to examine hefty purposes reminiscent of internet sites. InnoDB supports higher examine/write concurrency. the fresh Archive storage engine is designed for logging and archival statistics. The NDB storage engine offers very exorbitant efficiency and availability.

    One improvement of this design is that their clients had been capable of accomplish migrating from a legacy device to a SQL DBMS more straightforward by using changing their legacy storage prerogative into a MySQL storage engine, allowing them to challenge SQL queries in opposition t their legacy gear with out forsaking their obsolete techniques.

    Pluggable seems to suggest that they are utilized in inescapable circumstances, or now not at everyone depending on the administrator's needs. could you expound how some of the more essential engines (of the 9) support a MySQL DBA?

    Hillyer: listed below are a brace of examples:

    the brand fresh Archive engine is extraordinary for storing log facts because it makes disburse of gzip compression and indicates splendid efficiency for inserts and reads with concurrency aid. This skill an administrator can sustain on storage and processing costs for logging and archival facts.

    the fresh Blackhole engine is pleasing in that it takes everyone INSERT, supplant and DELETE statements and drops them; it literally holds no records. That might likewise materialize unusual at first, however it works neatly for enabling a replication master to deal with writes with out the disburse of any storage because the statements nevertheless glean written to the binary log and passed on to the slaves.

    due to the brand fresh pluggable element, these storage engines can be loaded into the server when mandatory, and unloaded when now not being used.

    Are any of the nine modules anything that has already been fragment of database expertise in the past? How does their inclusion in MySQL server accomplish this app extra robust?

    Hillyer: every one of these storage engines had been in vicinity for reasonably some time, namely MyISAM, InnoDB, BDB, recollection and MERGE. they are rather develope and used by using most of their clients. The NDB storage engine is fresh to MySQL, however is an latest technology that has been in edifice for over 10 years.

    The NDB storage engine is an illustration of a storage engine that has contributed to making MySQL extra powerful with the aid of enabling 5 nines of availability when effectively carried out.

    Are there any concerns with MySQL that these pluggable storage engines execute not handle? How essential is it that additional modules are launched in future types?

    Hillyer: there will always be needs that inescapable clients maintain that the existing storage engines will now not handle, but the fresh pluggable approach capacity that it might be increasingly elementary to consequence in writing customized storage engines in line with a defined API [application programming interface] and plug them in.

    As these engines are written, it should be enjoyable to glimpse the innovation that comes from the community, and i glimpse ahead to trying some of those neighborhood-provided storage engines.

  • Netflix Billing Migration to AWS — fragment II | true questions and Pass4sure dumps

    This is a continuation in the progression on Netflix Billing migration to the Cloud. An overview of the migration project was published earlier here:

    This post details the technical journey for the Billing applications and datastores as they were moved from the Data heart to AWS Cloud.

    As you might maintain read in earlier Netflix Cloud Migration blogs, everyone of Netflix streaming infrastructure is now completely sprint in the Cloud. At the rate Netflix was growing, especially with the imminent Netflix Everywhere launch, they knew they had to breeze Billing to the Cloud sooner than later else their existing legacy systems would not be able to scale.

    There was no doubt that it would be a monumental task of moving highly sensitive applications and captious databases without disrupting the business, while at the same time continuing to build the fresh industry functionality and features.

    A few key responsibilities and challenges for Billing:

  • The Billing team is responsible for the financially captious data in the company. The data they generate on a daily basis for subscription charges, gift cards, credits, chargebacks, etc. is rolled up to finance and is reported into the Netflix accounting. They maintain stringent SLAs on their daily processing to ensure that the revenue gets booked correctly for each day. They cannot tolerate delays in processing pipelines.
  • Billing has zero tolerance for data loss.
  • For most parts, the existing data was structured with a relational model and necessitates disburse of transactions to ensure an all-or-nothing behavior. In other words they exigency to be ACID for some operations. But they likewise had use-cases where they needed to be highly available across regions with minimal replication latencies.
  • Billing integrates with the DVD industry of the company, which has a different architecture than the Streaming component, adding to the integration complexity.
  • The Billing team likewise provides data to support Netflix Customer Service agents to respond any member billing issues or questions. This necessitates providing Customer support with a comprehensive view of the data.
  • The pass the Billing systems were, when they started this project, is shown below.

  • 2 Oracle databases in the Data Center — One storing the customer subscription information and other storing the invoice/payment data.
  • Multiple REST-based applications — Serving calls from the and Customer support applications. These were essentially doing the CRUD operations
  • 3 Batch applications — Subscription Renewal — A daily job that looks through the customer ground to determine the customers to be billed that day and the amount to be billed by looking at their subscription plans, discounts, etc.Order & Payment Processor — A progression of batch jobs that create an invoice to saturate the customer to be renewed and process the invoice through various stages of the invoice lifecycle.Revenue Reporting — A daily job that looks through billing data and generates reports for the Netflix Finance team to consume.
  • One Billing Proxy application (in the Cloud) — used to route calls from ease of Netflix applications in the Cloud to the Data Center.
  • Weblogic queues with legacy formats being used for communications between processes.
  • The goal was to breeze everyone of this to the Cloud and not maintain any billing applications or databases in the Data Center. everyone this without disrupting the industry operations. They had a long pass to go!

    The Plan

    We came up with a 3-step arrangement to execute it:

  • Act I — Launch fresh countries directly in the Cloud on the billing side while syncing the data back to the Data heart for legacy batch applications to continue to work.
  • Act II — Model the user-facing data, which could live with eventual consistency and does not exigency to be ACID, to persist to Cassandra (Cassandra gave us the ability to accomplish writes in one region and accomplish it available in the other regions with very low latency. It likewise gives us high-availability across regions).
  • Act III — Finally breeze the SQL databases to the Cloud.
  • In each step and for each country migration, learn from it, iterate and ameliorate on it to accomplish it better.

    Act I — Redirect fresh countries to the Cloud and sync data to the Data Center

    Netflix was going to launch in 6 fresh countries soon. They decided to remove it as a challenge to launch these countries partly in the Cloud on the billing side. What that meant was the user-facing data and applications would be in the Cloud, but they would silent exigency to sync data back to the Data heart so some of their batch applications which would continue to sprint in the Data heart for the time-being, could work without disruption. The customer for these fresh countries data would be served out of the Cloud while the batch processing would silent sprint out of the Data Center. That was the first step.

    We ported everyone the APIs from the 2 user-facing applications to a Cloud based application that they wrote using Spring Boot and Spring Integration. With Spring Boot, they were able to quickly jump-start edifice a fresh application, as it provided the infrastructure and plumbing they needed to stand it up out of the box and let us focus on the industry logic. With Spring Integration they were able to write once and reuse a lot of the workflow style code. likewise with headers and header-based routing support that it provided, they were able to implement a pub-sub model within the application to consequence a message in a channel and maintain everyone consumers consume it with independent tuning for each consumer. They were now able to ply the API calls for members in the 6 fresh countries in any AWS region with the data stored in Cassandra. This enabled Billing to be up for these countries even if an entire AWS region went down — the first time they were able to discern the power of being on the Cloud!

    We deployed their application on EC2 instances in AWS in multiple regions. They added a redirection layer in their existing Cloud proxy application to switch billing calls for users in the fresh countries to proceed to the fresh billing APIs in the Cloud and billing calls for the users in the existing countries to continue to proceed to the obsolete billing APIs in the Data Center. They opened direct connectivity from one of the AWS regions to the existing Oracle databases in the Data heart and wrote an application to sync the data from Cassandra via SQS in the 3 regions back to this region. They used SQS queues and departed note Queues (DLQs) to breeze the data between regions and process failures.

    New country launches usually intend a bump in member base. They knew they had to breeze their Subscription Renewal application from the Data heart to the Cloud so that they don’t consequence the load on the Data heart one. So for these 6 fresh countries in the Cloud, they wrote a crawler that went through everyone the customers in Cassandra daily and came up with the members who were to be charged that day. This everyone row iterator approach would work for now for these countries, but they knew it wouldn’t hold ground when they migrated the other countries and especially the US data (which had majority of their members at that time) to the Cloud. But they went ahead with it for now to test the waters. This would be the only batch application that they would sprint from the Cloud in this stage.

    We had chosen Cassandra as their data store to be able to write from any region and due to the mercurial replication of the writes it provides across regions. They defined a data model where they used the customerId as the key for the row and created a set of composite Cassandra columns to enable the relational aspect of the data. The picture below depicts the relationship between these entities and how they represented them in a separate column family in Cassandra. Designing them to be a fragment of a separate column family helped us achieve transactional support for these related entities.

    We designed their application logic such that they read once at the birth of any operation, updated objects in recollection and persisted it to a separate column family at the halt of the operation. Reading from Cassandra or writing to it in the middle of the operation was deemed an anti-pattern. They wrote their own custom ORM using Astyanax (a Netflix grown and open-sourced Cassandra client) to be able to read/write the domain objects from/to Cassandra.

    We launched in the fresh countries in the Cloud with this approach and after a brace of initial minor issues and bug fixes, they stabilized on it. So far so good!

    The Billing system architecture at the halt of Act I was as shown below:

    Act II — Move everyone applications and migrate existing countries to the cloud

    With Act I done successfully, they started focusing on moving the ease of the apps to the Cloud without moving the databases. Most of the industry logic resides in the batch applications, which had matured over years and that meant digging into the code for every condition and spending time to rewrite it. They could not simply forklift these to the Cloud as is. They used this break to remove departed code where they could, fracture out functional parts into their own smaller applications and restructure existing code to scale. These legacy applications were coded to read from config files on disk on startup and disburse other static resources infatuation reading messages from Weblogic queues — all anti-patterns in the Cloud due to the ephemeral nature of the instances. So they had to re-implement those modules to accomplish the applications Cloud-ready. They had to change some APIs to ensue an async pattern to allow moving the messages through the queues to the region where they had now opened a secure connection to the Data Center.

    The Cloud Database Engineering (CDE) team setup a multi node Cassandra cluster for their data needs. They knew that the everyone row Cassandra iterator Renewal solution that they had implemented for renewing customers from earlier 6 countries would not scale once they moved the entire Netflix member billing data to Cassandra. So they designed a system to disburse Aegisthus to tug the data from Cassandra SSTables and transmute it to JSON formatted rows that were staged out to S3 buckets. They then wrote Pig scripts to sprint mapreduce on the massive dataset everyday to fetch customer list to renew and saturate for that day. They likewise wrote Sqoop jobs to tug data from Cassandra and Oracle and write to Hive in a queryable format which enabled us to unite these two datasets in Hive for faster troubleshooting.

    To enable DVD servers to talk to us in the Cloud, they setup load balancer endpoints (with SSL client certification) for DVD to route calls to us through the Cloud proxy, which for now would pipe the muster back to the Data Center, until they migrated US. Once US data migration was done, they would sever the Cloud to Data heart communication link.

    To validate this huge data migration, they wrote a comparator utensil to compare and validate the data that was migrated to the Cloud, with the existing data in the Data Center. They ran the comparator in an iterative format, where they were able to identify any bugs in the migration, fix them, lucid out the data and re-run. As the runs became clearer and devoid of issues, it increased their aplomb in the data migration. They were excited to start with the migration of the countries. They chose a country with a minute Netflix member ground as the first country and migrated it to the Cloud with the following steps:

  • Disable the non-GET apis for the country under migration. (This would not repercussion members, but retard any updates to subscriptions in billing)
  • Use Sqoop jobs to glean the data from Oracle to S3 and Hive.
  • Transform it to the Cassandra format using Pig.
  • Insert the records for everyone members for that country into Cassandra.
  • Enable the non-GET apis to now serve data from the Cloud for the country that was migrated.
  • After validating that everything looked good, they moved to the next country. They then ramped up to migrate set of similar countries together. The final country that they migrated was US, as it held most of their member ground and likewise had the DVD subscriptions. With that, everyone of the customer-facing data for Netflix members was now being served through the Cloud. This was a tall milestone for us!

    After Act II, they were looking infatuation this:

    Act III — Good bye Data Center!

    Now the only (and most important) thing remaining in the Data heart was the Oracle database. The dataset that remained in Oracle was highly relational and they did not feel it to be a pleasant notion to model it to a NoSQL-esque paradigm. It was not possible to structure this data as a separate column family as they had done with the customer-facing subscription data. So they evaluated Oracle and Aurora RDS as possible options. Licensing costs for Oracle as a Cloud database and Aurora silent being in Beta didn’t assist accomplish the case for either of them.

    While the Billing team was industrious in the first two acts, their Cloud Database Engineering team was working on creating the infrastructure to migrate billing data to MySQL instances on EC2. By the time they started Act III, the database infrastructure pieces were ready, thanks to their help. They had to transmute their batch application code ground to be MySQL-compliant since some of the applications used simple jdbc without any ORM. They likewise got rid of a lot of the legacy pl-sql code and rewrote that logic in the application, stripping off departed code when possible.

    Our database architecture now consists of a MySQL master database deployed on EC2 instances in one of the AWS regions. They maintain a catastrophe Recovery DB that gets replicated from the master and will be promoted to master if the master goes down. And they maintain slaves in the other AWS regions for read only access to applications.

    Our Billing Systems, now completely in the Cloud, glimpse infatuation this:

    Needless to say, they erudite a lot from this huge project. They wrote a few tools along the pass to assist us debug/troubleshoot and ameliorate developer productivity. They got rid of obsolete and departed code, cleaned up some of the functionality and improved it wherever possible. They received support from many other engineering teams within Netflix. They had engineers from the Cloud Database Engineering, Subscriber and Account engineering, Payments engineering, Messaging engineering worked with us on this initiative for anywhere between 2 weeks to a brace of months. The powerful thing about the Netflix culture is that everyone has one goal in mind — to deliver a powerful sustain for their members everyone over the world. If that means helping Billing solution breeze to the Cloud, then everyone is ready to execute that irrespective of team boundaries!

    The road ahead…

    With Billing in the Cloud, Netflix streaming infrastructure now completely runs in the Cloud. They can scale any Netflix service on demand, execute predictive scaling based on usage patterns, execute single-click deployments using Spinnaker and maintain consistent deployment architectures between various Netflix applications. Billing infrastructure can now accomplish disburse of everyone the Netflix platform libraries and frameworks for monitoring and tooling support in the Cloud. Today they support billing for over 81 million Netflix members in 190+ countries. They generate and churn through terabytes of data everyday to accomplish billing events. Their road ahead includes rearchitecting membership workflows for a global scale and industry challenges. As fragment of their fresh architecture, they would be redefining their services to scale natively in the Cloud. With the global launch, they maintain an break to learn and redefine Billing and Payment methods in newer markets and integrate with many global partners and local payment processors in the regions. They are looking forward to architect more functionality and scale out further.

    If you infatuation to design and implement large-scale distributed systems for captious data and build automation/tooling for testing it, they maintain a brace of positions open and would fancy to talk to you! Check out the positions here :

    Performance Certification of Couchbase Autonomous Operator on Kubernetes | true questions and Pass4sure dumps

    At Couchbase, they remove performance very seriously, and with the launch of their fresh product, Couchbase Autonomous Operator 1.0, they wanted to accomplish sure it’s Enterprise-grade and production ready for customers.

    In this post, they will contend the circumstantial performance results from running YCSB Performance Benchmark tests on Couchbase Server 5.5 using the Autonomous Operator to deploy on Kubernetes platform. One of the tall concerns for Enterprises planning to sprint a database on Kubernetes is "performance."

    This document gives a quick comparison of two workloads, namely YCSB A & E with Couchbase Server 5.5 on Kubernetes vs. bare metal.

    YCSB Workload A: This workload has a fuse of 50/50 reads and writes. An application illustration is a session store recording recent actions.

    Workload E: Short ranges: In this workload, short ranges of records are queried, instead of individual records. Application example: threaded conversations, where each scan is for the posts in a given thread (assumed to be clustered by thread id).

    In general, they observed no significant performance degradation in running Couchbase Cluster on Kubernetes, Workload A had on par performance compared to bare metal and Workload E had approximately less than 10% degradation.


    For the setup, Couchbase was installed using the Operator deployment as stated below. For more details on the setup, tickle mention here.


    Operator deployment: deployment.yaml (See Appendix)

    Couchbase deployment: couchbase-cluster-simple-selector.yaml (See Appendix)
