Our founder and Principal Shiv Iyer did a webinar (July 09, 2020) on PostgreSQL Internals and Performance Optimization  , Shiv is a longtime Open Source Database Systems Operations expert with core expertise on performance optimization, capacity planning / sizing, architecture / internals, transaction processing engineering, horizontal scalability & partitioning, storage optimization, distributed database systems and data compression algorithms. The core objective of this webinar was to talk about PostgreSQL internals, troubleshooting PostgreSQL query performance, index optimization, partitioning, PostgreSQL configuration parameters and best practices. We strongly believe that understanding PostgreSQL architecture and internals are very important to troubleshoot PostgreSQL performance proactively and efficiently, You can download the PDF copy of the webinar here , If you want the recorded video of the webinar please contact support@minervadb.com .

There can be several reasons for a MySQL database outage: hardware failure, power outage, human error, natural disaster etc. We may not be able prevent all the disaster from happening but investing on a robust disaster recovery plan is very important for building fault-tolerant database infrastructure operations on MySQL.  Every MySQL DBA is accountable for developing a disaster recovery plan addressing data sensitivity, data loss tolerance and data security. Join Shiv Iyer, Founder and Principal of MinervaDB to lean about the best practices for building highly reliable MySQL DR strategy and operations on Thursday, June 18, 2020 – 06:00 PM to 07:00 PM PDT. Building DR for a high traffic MySQL database infrastructure means deep understanding of multiple backup strategies and choosing optimal ones which are best suited for performance and reliability. Most of the data intensive MySQL infrastructure will have a combination of multiple backup methods and tools, In this webinar Shiv talks about his experiences in the past and present on building MySQL DR Ops, tools and zero tolerance data loss methods.

Join this webinar to learn more about:

• Proactive MySQL DR – From strategy to execution
• Building capacity for reliable MySQL DR
• MySQL DR strategies
• MySQL Backup tools
• Managing MySQL DR Ops. for very large databases
• Testing MySQL Backups
• Biggest MySQL DR mistakes
• MySQL DR Best Practices and Checklist

Recently ( on Friday, 5 June 2020 – 06:00 PM PDT to 06:45 PM PDT  ) our Founder and Principal ( Shiv Iyer ) did a webinar on building Database Systems Infrastructure Operations for Performance and Reliability. In this webinar, he discussed about capacity planning / sizing, observability & resilience, performance audit / health-check / diagnostics / forensics, performance optimization & tuning and building highly available / fault-tolerant / self-healing systems architecture. You can download the PDF of the webinar here . Thanks for joining the webinar and making it a success, Looking forward to seeing you all in the next webinar.

MariaDB 10.4 has several interesting new features solving database performance and reliability concerns, You can learn more about MariaDB 10.4 new features here . In this post we want to share with you how MariaDB 10.4 has much safer MariaDB Server Shutdown options. So what happens you shutdown ( normal ) MariaDB Server (Master instance ) in a replication infrastructure ? MariaDB Master kills all the client threads in a random order. Technically, MariaDB Server considers binary log dump threads also as client threads so it will also get killed while client threads still exists and this causes a serious Data Reliability risk because data which can be written on the master during normal shutdown won’t be replicated to slave. This unacceptable for several business models which has zero tolerance on data loss.  Unfortunately, This happens even when you have deployed MariaDB semi-synchronous replication solution considering more reliable High Availability strategies, How MariaDB 10.4 is solving this problem ?

In MariaDB 10.4 and later you can shutdown MariaDB Server with option WAIT FOR ALL SLAVES –  Which means, MariaDB server only kills its binary log dump threads after all client threads have been killed, and it only completes the shutdown after the last binary log has been sent to all connected slaves. You can shutdown MariaDB 10.4 server using either the mysqladmin utility or the SHUTDOWN command, and providing a special option as copied below:

mysqladmin --wait-for-all-slaves shutdown

Shutdown MariaDB 10.4 by providing the WAIT FOR ALL SLAVES option to the command:

SHUTDOWN WAIT FOR ALL SLAVES;

This solution is still not solving concerns related to MariaDB Server 10.4 crash or shutdown from server tools like systemd or sysVinit as we can’t enable this feature by default, So we are expecting more improvements here going forward.

P.S. – If you are using MariaDB 10.3 or/ and before, we strongly recommend to switchover slaves to new master before shutting down the old master. Thanks for spending time in reading this post and your comments are welcome.
