What is the value in allowing the use of malloc implementations that cause segfaults? :) > Make SerializingCache Memory Pluggable > -------------------------------------- > > Key: CASSANDRA-3997 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3997 > Project: Cassandra > Issue Type: Improvement > Components: Core > Affects Versions: 1.2 > Reporter: Vijay > Assignee: Vijay > Priority: Minor > Labels: cache > Fix For: 1.2 > > Attachments: jna.zip > > > Serializing cache uses native malloc and free by making FM pluggable, users will have a choice of gcc malloc, TCMalloc or JEMalloc as needed. > Initial tests shows less fragmentation in JEMalloc but the only issue with it is that (both TCMalloc and JEMalloc) are kind of single threaded (at-least they crash in my test otherwise). -- This message is automatically generated by JIRA.
