Problem summary
gperftools/tcmalloc[https://github.com/gperftools/gperftools] is outdated, there are no new features for many years, only fix bugs. doris is currently used by default.google/tcmalloc[https://github.com/google/tcmalloc], very active recently, has many new features, and is expected to perform better than jemalloc, but there is currently no stable version.Moreover, the compilation dependencies are complex and difficult to integrate, and are incompatible with
gperftools/tcmalloc, and there are few reference documents.jemalloc[https://github.com/jemalloc/jemalloc] performs better thangperftools/tcmallocunder high concurrency, and is mature and stable, looking forward to being the default memory allocator.Tested in Doris: #12496
