Method Detail

getPartitioner

public final AbstractCassandraStoreManager.Partitioner getPartitioner()

getCassandraPartitioner

public abstract org.apache.cassandra.dht.IPartitioner<? extends org.apache.cassandra.dht.Token<?>> getCassandraPartitioner()
                                                                                                                    throws BackendException

Throws:

BackendException

beginTransaction

public StoreTransaction beginTransaction(BaseTransactionConfig config)

Specified by:

beginTransaction in interface StoreManager

toString

public String toString()

Overrides:

toString in class DistributedStoreManager

getFeatures

public StoreFeatures getFeatures()

Specified by:

getFeatures in interface StoreManager

getCompressionOptions

public abstract Map<String,String> getCompressionOptions(String cf)
                                                  throws BackendException

Returns a map of compression options for the column family cf. The contents of the returned map must be identical to the contents of the map returned by CfDef.getCompression_options(), even for implementations of this method that don't use Thrift.

Parameters:

cf - the name of the column family for which to return compression options

Returns:

map of compression option names to compression option values

Throws:

BackendException - if reading from Cassandra fails

getName

public String getName()

Specified by:

getName in interface StoreManager
