-----------------------------------------
Summary: Avoid allocating over-large bloom filters
Key: CASSANDRA-5906
URL: https://issues.apache.org/jira/browse/CASSANDRA-5906
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jonathan Ellis
Assignee: Yuki Morishita
Priority: Minor
Fix For: 2.0.1
We conservatively estimate the number of partitions post-compaction to be the
total number of partitions pre-compaction. That is, we assume the worst-case
scenario of no partition overlap at all.
This can result in substantial memory wasted in sstables resulting from highly
overlapping compactions.
