Percona Live 2018 Community Report

So, after a whirlwind few days, Percona Live 2018 has been and gone. There was a great energy about the conference, and it was fantastic to meet so many open source database enthusiasts and supporters. A few things that I experienced:

  • Your great willingness to share knowledge. It was a fantastic place to learn for those who have experience from a different field of technology. Almost everyone seemed to be very open and generous with their time.
  • The “superstars” from our industry are not so scary. They are as willing to be open and generous with their experience and views as any of the other attendees, and equally as interested in making new discoveries.
  • There aren’t many times you can sit down to a (community) dinner, to share food and anecdotes with people from USA, UK, Germany and Armenia at the same time. I thoroughly enjoyed the company, …

MyRocks, malloc and fragmentation -- a strong case for jemalloc

While trying to reproduce a MyRocks performance problem I ran a test using a 4gb block cache and tried both jemalloc and glibc malloc. The test server uses Ubuntu 16.04 which has glibc 2.23 today. The table below lists the VSZ and RSS values for the mysqld process after a test table has been loaded. RSS with glibc malloc is 2.6x larger than with jemalloc. MyRocks and RocksDB are much harder on an allocator than InnoDB and this test shows the value of jemalloc.

VSZ(gb) RSS(gb) malloc    7.9     4.8    jemalloc-3.6.0 13.6    12.4    glibc-2.23
I am not sure that it is possible to use a large RocksDB block cache with glibc malloc, where large means that it gets about 80% of RAM.

I previously shared results  …
