Summary: Memory Management
Key: HBASE-15555
URL: https://issues.apache.org/jira/browse/HBASE-15555
Project: HBase
Issue Type: Umbrella
Reporter: stack
Umbrella issue on memory management. One-stop shop to learn how we're doing it,
tenets, and work to be done
Subtasks include:
+ Map of memory allocation and recycling landscape
+ Where are we allocating when we could be recycling
+ MSLAB and G1GC don't go together?
+ Enable MSLAB pool always?
+ With offheap allocations, less GC but it runs for longer?
+ Better heuristics recycling: e.g. HBASE-15525 OutOfMemory could occur when
using BoundedByteBufferPool during RPC bursts
+ See if can do DFSClient buffer reuse: HBASE-15506 FSDataOutputStream.write()
allocates new byte buffer on each operation
What else?
