Transactions can -span multiple regions. Transaction writes are applied when committing a -transaction. At commit time, the transaction is examined to see if it -can be applied while still maintaining atomicity. This is done by -looking for conflicts with the transactions that committed while the -current transaction was running. This technique is known as optimistic -concurrency control (OCC) because it relies on the assumption that -transactions will mostly not have conflicts with each other. - -

    -For more details on OCC, see the paper On Optimistic Methods for Concurrency Control -by Kung and Robinson available - here . - -

    To enable transactions, modify hbase-site.xml to turn on the -TransactionalRegionServer. This is done by setting -hbase.regionserver.class to -org.apache.hadoop.hbase.ipc.TransactionalRegionInterface and -hbase.regionserver.impl to -org.apache.hadoop.hbase.regionserver.transactional.TransactionalRegionServer - -

    -The read set claimed by a transactional scanner is determined from the start and - end keys which the scanner is opened with. - - - -

    Known Issues

    - -Recovery in the face of hregion server failure -is not fully implemented. Thus, you cannot rely on the transactional -properties in the face of node failure. - - - - - - diff --git a/src/java/org/apache/hadoop/hbase/filter/ColumnValueFilter.java b/src/java/org/apache/hadoop/hbase/filter/ColumnValueFilter.java index ff9a2fc06d3..c8a9ae316e1 100644 --- a/src/java/org/apache/hadoop/hbase/filter/ColumnValueFilter.java +++ b/src/java/org/apache/hadoop/hbase/filter/ColumnValueFilter.java @@ -33,12 +33,15 @@ import org.apache.hadoop.hbase.io.Cell; import org.apache.hadoop.io.ObjectWritable; /** + * This filter is a no-op in HBase 0.20.
