Using jemalloc to optimize memory usage
Apama supports the jemalloc memory allocator as an optional alternative to its standard memory allocator. See also
http://jemalloc.net/.
Note: This option is only available on Linux platforms and is not available on Windows at this time.
jemalloc typically consumes less memory overall. Therefore, it is advisable to use it when the process needs excessive memory or is running out of memory. But keep in mind that there may be throughput, latency or overall performance hits if you use this option.
To enable jemalloc as the memory allocator, set the following environment variable before starting the correlator:
AP_ALLOCATOR=jemalloc
