java.lang.Object org.springframework.data.hadoop.hbase.HbaseSynchronizationManager
public abstract class HbaseSynchronizationManager
Synchronization manager handling the tracking of Hbase resources (specifically tables). Used either manually or through HbaseInterceptor
to bind a table to the thread.
Each subsequent call made through HbaseTemplate
is aware of the table bound and will use it instead of retrieving a new instance.
