DOAN DuyHai updated CASSANDRA-11383:
------------------------------------
Description:
13 bare metal machines
- 6 cores CPU (12 HT)
- 64Gb RAM
- 4 SSD in RAID0
JVM settings:
- G1 GC
- Xms32G, Xmx32G
Data set:
- ≈ 100Gb/per node
- 1.3 Tb cluster-wide
- ≈ 20Gb for all SASI indices
C* settings:
- concurrent_compactors: 1
- compaction_throughput_mb_per_sec: 256
- memtable_heap_space_in_mb: 2048
- memtable_offheap_space_in_mb: 2048
I created 9 SASI indices
- 8 indices with text field, NonTokenizingAnalyser, PREFIX mode,
case-insensitive
- 1 index with numeric field, SPARSE mode
After a while, the nodes just gone OOM.
I attach log files. You can see a lot of GC happening while index segments are
flush to disk. At some point the node OOM ...
