Hi Team,
Our partner has received response from our support team about Vertica node down (48-node cluster) to change default from "malloc" to "jemalloc" by changing symbolic link. However, they've few questions as below.
- Vertica has been including jemalloc library since v8.0(/opt/vertica/lib/libjemalloc.so)
So, Can I use that library without compiling?
- Why Vertica doesn't use jemalloc as default, despite including jemalloc library?
Thank you.
Support should have provided all the instructions to launch vertica using jemalloc, it's a dynamic library so there is no need to recompile. Jemalloc is a little bit slower than the allocator in glibc, but under some circumstances it does a better job managing memory.
There's OOM issue and make some nodes down. After investigated, support team suggested to use jemalloc.
Thank you for information.
