Method Detail

createBulkMutation

public BulkMutationWrapper createBulkMutation(String tableId)

Description copied from interface: DataClientWrapper

Creates instance of bulkMutation with specified table ID.

Specified by:

createBulkMutation in interface DataClientWrapper

createBulkRead

public BulkReadWrapper createBulkRead(String tableId)

Description copied from interface: DataClientWrapper

Creates BulkReadWrapper with specified table ID.

The BulkRead instance will be scoped to a single user visible operation. The operation timeout (which is configured in the settings) is started from the time the createBulkRead is invoked.

 try (BulkReadWrapper batch = wrapper.createBulkRead(tableId)) {
   batch.add(key1, filter1);
   batch.add(key2, filter2);
 }
 

Specified by:

createBulkRead in interface DataClientWrapper

mutateRowAsync

public com.google.api.core.ApiFuture<Void> mutateRowAsync(com.google.cloud.bigtable.data.v2.models.RowMutation rowMutation)

Description copied from interface: DataClientWrapper

Mutate a row atomically.

Specified by:

mutateRowAsync in interface DataClientWrapper

readModifyWriteRowAsync

public com.google.api.core.ApiFuture<org.apache.hadoop.hbase.client.Result> readModifyWriteRowAsync(com.google.cloud.bigtable.data.v2.models.ReadModifyWriteRow readModifyWriteRow)

Description copied from interface: DataClientWrapper

Perform an atomic read-modify-write operation on a row.

Specified by:

readModifyWriteRowAsync in interface DataClientWrapper

checkAndMutateRowAsync

public com.google.api.core.ApiFuture<Boolean> checkAndMutateRowAsync(com.google.cloud.bigtable.data.v2.models.ConditionalRowMutation conditionalRowMutation)

Description copied from interface: DataClientWrapper

Mutate a row atomically dependent on a precondition.

Specified by:

checkAndMutateRowAsync in interface DataClientWrapper

sampleRowKeysAsync

public com.google.api.core.ApiFuture<List<com.google.cloud.bigtable.data.v2.models.KeyOffset>> sampleRowKeysAsync(String tableId)

Description copied from interface: DataClientWrapper

Sample row keys from a table, returning a Future that will complete when the sampling has completed.

Specified by:

sampleRowKeysAsync in interface DataClientWrapper
