Skip large size (Configurable) SSTable in minor or/and major compaction
-----------------------------------------------------------------------
Key: CASSANDRA-1041
URL: https://issues.apache.org/jira/browse/CASSANDRA-1041
Project: Cassandra
Issue Type: New Feature
Components: Core
Reporter: Schubert Zhang
Priority: Minor
When the SSTable files are large enough, such as 100GB, the compaction (include
minor and major) cost is big (disk IO, CPU, memory), etc.
In some applications, we accept not compcating all SSTables to the final very
large ones.
This feature provide two optional configurable attributes MinorCompactSkipInGB
and MajorCompactSkipInGB for each ColumnFamily.
The optional MinorCompactSkipInGB attribute specifies the maximum size of
SSTables which will be compcated in minor-compaction. The SSTables larger than
MinorCompactSkipInGB will be skipped. The optional MajorCompactSkipInGB
attribute is same for major-compaction.
The default of these attributes are 0, means do not skip, just as current 0.6.1.
