MariaDB-5.5.21-beta is the first MariaDB release featuring the new thread pool. Oracle offers a commercial thread pool plugin for MySQL Enterprise, but now MariaDB brings a thread pool implementation to the community!
If you are not familiar with the term, please read the Knowledge Base article about it.
The main design goal of the thread pool is to increase the scalability of the MariaDB server with many concurrent connections. In order to test and demonstrate this, I have run the sysbench OLTP RO benchmark with up to 4096 threads to compare the new pool-of-threads and the traditional thread-per-connection scheduler:
Benchmark description:
- sysbench multi table OLTP, readonly
- 16 tables, totaling 40 mio rows (~10G of data)
- 16G buffer pool – result is independent of disk performance
- mysqld bound to 16 cpu cores, sysbench to the other 8
Read/write OLTP benchmark results will be published as soon as they are available. …
