Table Method Support

This table indicates which methods HPE Ezmeral Data Fabric Database supports in the HBase interface Table.

The following HBase methods are supported with HPE Ezmeral Data Fabric Database tables, except where noted. For full details about this interface, see Interface Table in the Client package.

Method Name Modifier and Type Description Supported?
append(Append append) Result Appends values to one or more columns within a single row. Yes
batch(List<? extends Row> actions) Object[] A batch call on Deletes, Gets, Puts, Increments, Appends and RowMutations. Deprecated

checkAndDelete(byte[] row, byte[] family, byte[] qualifier, CompareFilter.CompareOp compareOp, byte[] value, Delete delete) boolean Yes
checkAndMutate(byte[] row, byte[] family, byte[] qualifier, CompareFilter.CompareOp compareOp, byte[] value, RowMutations mutation) boolean Yes
checkAndPut(byte[] row, byte[] family, byte[] qualifier, byte[] value, Put put) boolean Yes
checkAndPut(byte[] row, byte[] family, byte[] qualifier, CompareFilter.CompareOp compareOp, byte[] value, Put put) boolean Yes
close() void Releases any resources held or pending changes in internal buffers. Yes
coprocessorService(byte[] row) CoprocessorRpcChannel Creates and returns a RpcChannel instance connected to the table region containing the specified row. No
coprocessorService(Class<T> service, byte[] startKey, byte[] endKey, org.apache.hadoop.hbase.client.coprocessor.Batch.Call<T,R> callable, org.apache.hadoop.hbase.client.coprocessor.Batch.Callback<R> callback) <T extends com.google.protobuf.Service,R> void Creates an instance of the given Service subclass for each table region spanning the range from the startKey row to endKey row (inclusive), and invokes the passed Batch.Call.call(T) method with each Service instance. No
coprocessorService(Class<T> service, byte[] startKey, byte[] endKey, org.apache.hadoop.hbase.client.coprocessor.Batch.Call<T,R> callable) <T extends com.google.protobuf.Service,R> Map<byte[],R> No
delete(Delete delete) void Deletes the specified cells/row. Yes
delete(List<Delete> deletes) void Deletes the specified cells/rows in bulk. Yes
exists(Get get) boolean Test for the existence of columns in the table, as specified by the Get. Yes
existsAll(List<Get> gets) boolean[] Test for the existence of columns in the table, as specified by the Gets, in batch. Yes
get(Get get) Result Extracts certain cells from a given row. Yes
get(List<Get> gets) Result[] Extracts certain cells from the given rows, in batch. Yes
getConfiguration() org.apache.hadoop.conf.Configuration Returns the Configuration object used by this instance. Yes
getName() TableName Gets the fully qualified table name instance of this table. Yes

getScanner(byte[] family) ResultScanner Gets a scanner on the current table for the given family. Yes
getScanner(Scan scan) ResultScanner Returns a scanner on the current table as specified by the Scan object. Yes
getTableDescriptor() HTableDescriptor Gets the table descriptor for this table. Yes
getWriteBufferSize() long Returns the maximum size in bytes of the write buffer for this HTable. No
increment(Increment increment) Result Increments one or more columns within a single row. Yes
incrementColumnValue(byte[] row, byte[] family, byte[] qualifier, long amount, Durability durability) long Atomically increments a column value. Yes
incrementColumnValue(byte[] row, byte[] family, byte[] qualifier, long amount) long See incrementColumnValue(byte[], byte[], byte[], long, Durability). Yes
mutateRow(RowMutations rm) void Performs multiple mutations atomically on a single row. Yes
put(List<Put> puts) void Puts some data in the table, in batch. Yes
