co.cask.tephra.hbase96.coprocessor.TransactionVisibilityFilter

{@code org.apache.hadoop.hbase.coprocessor.RegionObserver} coprocessor that handles server-side processingfor transactions:

applies filtering to exclude data from invalid and in-progress transactions
overrides the scanner returned for flush and compaction to drop data written by invalidated transactions, or expired due to TTL.

In order to use this coprocessor for transactions, configure the class on any table involved in transactions, or on all user tables by adding the following to hbase-site.xml: {@code hbase.coprocessor.region.classes co.cask.tephra.hbase96.coprocessor.TransactionProcessor }

HBase {@code Get} and {@code Scan} operations should have the current transaction serialized on to the operationas an attribute: {@code Transaction t = ...; Get get = new Get(...); TransactionCodec codec = new TransactionCodec(); codec.addToOperation(get, t);}

    return new DefaultTransactionStateCacheSupplier(tableNamespace, env.getConfiguration());
  }


  @Override
  protected Filter getTransactionFilter(Transaction tx) {
    return new TransactionVisibilityFilter(tx, ttlByFamily, allowEmptyValues, new IncrementFilter());
  }

    return new DefaultTransactionStateCacheSupplier(tableNamespace, env.getConfiguration());
  }


  @Override
  protected Filter getTransactionFilter(Transaction tx) {
    return new TransactionVisibilityFilter(tx, ttlByFamily, allowEmptyValues, new IncrementFilter());
  }
