Welcome to the free open-source OLAP server project
eMondrian is a free open-source OLAP server. It is based on the Mondrian project. OLAP server allows you to represent your database as a multidimensional space with dimensions and measures. It hides the complexity of underlying tables and their relations and allows you to interactively analyze data from multiple perspectives. eMondrian server can run on Windows and Linux operating systems.

Note that glibc has a similar problem in multithreaded contexts. It strands unused memory in thread-local pools, which grows your memory usage over time like a memory leak. We got lower memory usage that didn't grow over time by switching to jemalloc.
Example of this: https://github.com/prestodb/presto/issues/8993
