HBase Region Major Compaction +

The time between major compactions of all HStoreFiles in a region. Set to 0 to disable +automated major compactions.

+

 

Table 3.15. HBase Settings: General

NameNotes
+

HBase HStore compaction threshold

+		 +

When HStoreFiles in any one HStore are greater than this number, a compaction is run to rewrite all HStoreFiles files as one.

+
+

HFile block cache size

+		 +

Percentage of maximum heap (-Xmx setting) to allocate to block cache used by HFile/StoreFile. You can set this to 0 to disable but this is not a recommended practice.

+
+

Maximum HStoreFile Size

+		 +

If any one of a column families' HStoreFiles grows to exceed this value, the hosting HRegion +is split in two.

+
+

HBase Client Scanner Caching

+		 +

Number of rows that will be fetched when calling next on a scanner if it is not served from (local, client) memory. Do not set this value such that the time between invocations is greater than the scanner timeout

+
+

HBase passes this to the zk quorum as suggested maximum time for a session.

+
+

HBase Client Maximum key-value Size

+		 +

Specifies the combined maximum allowed size of a KeyValue instance. It should be set to a +fraction of the maximum region size.
