Method Detail

configureIndexTable

protected void configureIndexTable(org.apache.accumulo.core.client.Connector connector,
                       String tableName)
                            throws org.apache.accumulo.core.client.AccumuloSecurityException,

                                   org.apache.accumulo.core.client.TableNotFoundException

Utility method to update the correct iterators to the index table.

Parameters:

connector -

Throws:

org.apache.accumulo.core.client.AccumuloSecurityException

org.apache.accumulo.core.client.AccumuloException

org.apache.accumulo.core.client.TableNotFoundException

configureShardTable

protected void configureShardTable(org.apache.accumulo.core.client.Connector connector,
                       String tableName)
                            throws org.apache.accumulo.core.client.AccumuloSecurityException,
                                   org.apache.accumulo.core.client.AccumuloException,
                                   org.apache.accumulo.core.client.TableNotFoundException

Utility method to update the correct iterators to the shard table.

Parameters:

connector -

Throws:

org.apache.accumulo.core.client.AccumuloSecurityException

org.apache.accumulo.core.client.AccumuloException

org.apache.accumulo.core.client.TableNotFoundException

shutdown

public void shutdown()
              throws org.apache.accumulo.core.client.MutationsRejectedException

Free up any resources used by the store.

Throws:

org.apache.accumulo.core.client.MutationsRejectedException

save

public void save(Iterable<StoreEntry> events)

Events get save into a sharded table to parallelize queries & ingest. Since the data is temporal by default, an index table allows the lookup of events by UUID only (when the event's timestamp is not known).

Specified by:

save in interface EventStore

Parameters:

events -

Throws:

Exception

query

public org.calrissian.mango.collect.CloseableIterable<StoreEntry> query(Date start,
                                                               Date end,
                                                               org.calrissian.mango.criteria.domain.Node node,
                                                               Auths auths)

Query the store using criteria specified

Specified by:

query in interface EventStore

Returns:

get

public StoreEntry get(String uuid,
             Auths auths)

Get a specific StoreEntry with the given ID

Specified by:

get in interface EventStore

Returns:
