<name>hbase.hstore.compactionThreshold</name>

<value>3</value>
|
|
<description>
|
|
If more than this number of HStoreFiles in any one HStore
|
|
(one HStoreFile is written per flush of memstore) then a compaction
|
|
is run to rewrite all HStoreFiles files as one. Larger numbers
|
|
put off compaction but when it runs, it takes longer to complete.
|
|
During a compaction, updates cannot be flushed to disk. Long
|
|
compactions require memory sufficient to carry the logging of
|
|
all updates across the duration of the compaction.
|
|
|
|
If too large, clients timeout during compaction.
