Re: tcmalloc mysql 5.7.14

    We are having an issue with memory allocations on mysql 5.7.14 whereby
mysql is not releasing the memory that is being allocated during
mysqldump processes.

     This has been logged as a bug with mysql dev team however they do not
see this as a bug and suggested we test using another malloc library
such as tcmalloc.

    However from what I can see, this is no longer included in mysql 5.7
and thus I am trying to find out if anyone can tell me how to enable /
install this and how to tell mysql to use this library.

does the oracle stuff not support "jemalloc" like MariaDB

MariaDB even suppports "-DWITH_JEMALLOC=system" because it's not the job of random software ship and build random library sources in their tarballs which usually don't get much attention in case of updates (others than system packages)
