Senior Software Engineer - PostgreSQL Consultant
Ibrar Ahmed is a Software Architect in Percona LLC. Prior to coming to open source development, he had vast experience in software design and development. His main focus was on system-level embedded development. After joining EnterpriseDB in 2006, an Enterprise PostgreSQL company, he started his career in open source development specifically in PostgreSQL. He has contributed to the PostgreSQL community as well as other open source communities. His contribution ranges from the main performance feature enhancements to various PostgreSQL modules. In the database field, he has experience in other well-known databases MySQL, Oracle, and NoSQL databases such as MongoDB and Hadoop. His experience is not limited to core databases, but with the tools related to databases like Hive, HBase, and Spark. He also worked on integrating these tools with PostgreSQL.
Ibrar gave more than fifteen PostgreSQL talks in the last year in various parts of the World (PostgreConf-EU, PostgreConf-ASIA, PostgreConf-NY, Percona Lives, FOSDEM, etc ). He also authored multiple books on PostgreSQL.
PostgreSQL is one of the leading open-source databases. Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. The default configuration is designed in such a way that PostgreSQL can run on any system using minimum resources. Consequently, a default installation of PostgreSQL does not give optimum performance on the high-performance machine because it is set up to use all available resources.
PostgreSQL provides mechanisms that allow you to tune your database according to your workload and machine specification. Outside of PostgreSQL, though, we can tune the Linux kernel to allow the database load to work optimally. In this talk, we will learn how to tune some of the PostgreSQL’s parameters, and we will see the effect of that tuning, but we will focus on demonstrating how to tune Linux for better Postgres performance. As there are so many Linux kernel parameters that can be tuned to improve the performance of PostgreSQL, I will also share the results of benchmarks obtained when tuning some of the Linux parameters.
