            throws IOException,
                   InterruptedException

Method that does a batch call on Deletes, Gets, Puts, Increments, Appends, RowMutations. The ordering of execution of the actions is not defined. Meaning if you do a Put and a Get in the same batch(java.util.List<? extends org.apache.hadoop.hbase.client.Row>, java.lang.Object[]) call, you will not necessarily be guaranteed that the Get returns what the Put had put.

Parameters:

actions - list of Get, Put, Delete, Increment, Append, RowMutations.

results - Empty Object[], same size as actions. Provides access to partial results, in case an exception is thrown. A null in the result array means that the call for that action failed, even after retries. The order of the objects in the results array corresponds to the order of actions in the request list. n * @since 0.90.0

Throws:

IOException

InterruptedException

Throws:

IOException

InterruptedException

Since:

0.96.0

get

default Result get(Get get)
            throws IOException

Extracts certain cells from a given row.

Parameters:

get - The object that specifies what data to fetch and from which row.

Returns:

The data coming from the specified row, if it exists. If the row specified doesn't exist, the Result instance returned won't contain any KeyValue, as indicated by Result.isEmpty().

Throws:

IOException - if a remote or network exception occurs.

Since:

0.20.0

get

default Result[] get(List<Get> gets)
              throws IOException

Extracts specified cells from the given rows, as a batch.

Parameters:

gets - The objects that specify what data to fetch and from which rows.

Returns:

The data coming from the specified rows, if it exists. If the row specified doesn't exist, the Result instance returned won't contain any Cells, as indicated by Result.isEmpty(). If there are any failures even after retries, there will be a null in the results' array for those Gets, AND an exception will be thrown. The ordering of the Result array corresponds to the order of the list of passed in Gets.

Throws:

IOException - if a remote or network exception occurs.

Since:

0.90.0

API Note:

put(List) runs pre-flight validations on the input list on client. Currently get(List) doesn't run any validations on the client-side, currently there is no need, but this may change in the future. An IllegalArgumentException will be thrown in this case.

getScanner

default ResultScanner getScanner(Scan scan)
                          throws IOException

Returns a scanner on the current table as specified by the Scan object. Note that the passed Scan's start row and caching properties maybe changed.

put

default void put(List<Put> puts)
          throws IOException

Batch puts the specified data into the table.

This can be used for group commit, or for submitting user defined batches. Before sending a batch of mutations to the server, the client runs a few validations on the input list. If an error is found, for example, a mutation was supplied but was missing it's column an IllegalArgumentException will be thrown and no mutations will be applied. If there are any failures even after retries, a RetriesExhaustedWithDetailsException will be thrown. RetriesExhaustedWithDetailsException contains lists of failed mutations and corresponding remote exceptions. The ordering of mutations and exceptions in the encapsulating exception corresponds to the order of the input list of Put requests.

Parameters:

puts - The list of mutations to apply.

Throws:

IOException - if a remote or network exception occurs.

Deprecated. Since 2.0.0. Will be removed in 3.0.0. Use checkAndMutate(byte[], byte[])

Atomically checks if a row/family/qualifier value matches the expected value. If it does, it adds the put. If the passed value is null, the check is for the lack of column (ie: non-existence) The expected value argument of this call is on the left and the current value of the cell is on the right side of the comparison operator. Ie. eg. GREATER operator means expected value > existing <=> add the put.

Parameters:

row - to check

family - column family to check

qualifier - column qualifier to check

op - comparison operator to use

IOException - if a remote or network exception occurs.

Since:

0.20.0

delete

default void delete(List<Delete> deletes)
             throws IOException

Batch Deletes the specified cells/rows from the table.

If a specified row does not exist, Delete will report as though sucessful delete; no exception will be thrown. If there are any failures even after retries, a RetriesExhaustedWithDetailsException will be thrown. RetriesExhaustedWithDetailsException contains lists of failed Deletes and corresponding remote exceptions.

Parameters:

deletes - List of things to delete. The input list gets modified by this method. All successfully applied Deletes in the list are removed (in particular it gets re-ordered, so the order in which the elements are inserted in the list gives no guarantee as to the order in which the Deletes are executed).

Throws:

IOException - if a remote or network exception occurs. In that case the deletes argument will contain the Delete instances that have not be successfully applied.

Since:

0.20.1

API Note:

In 3.0.0 version, the input list deletes will no longer be modified. Also, put(List) runs pre-flight validations on the input list on client. Currently delete(List) doesn't run validations on the client, there is no need currently, but this may change in the future. An * IllegalArgumentException will be thrown in this case.

default CheckAndMutateResult checkAndMutate(CheckAndMutate checkAndMutate)
                                     throws IOException

checkAndMutate that atomically checks if a row matches the specified condition. If it does, it performs the specified action.

Parameters:

checkAndMutate - The CheckAndMutate object.

Returns:

A CheckAndMutateResult object that represents the result for the CheckAndMutate.

Throws:

IOException - if a remote or network exception occurs.

checkAndMutate

default List<CheckAndMutateResult> checkAndMutate(List<CheckAndMutate> checkAndMutates)
                                           throws IOException

Batch version of checkAndMutate. The specified CheckAndMutates are batched only in the sense that they are sent to a RS in one RPC, but each CheckAndMutate operation is still executed atomically (and thus, each may fail independently of others).

Parameters:

checkAndMutates - The list of CheckAndMutate.

Returns:

A list of CheckAndMutateResult objects that represents the result for each CheckAndMutate.

Throws:

IOException - if a remote or network exception occurs.

mutateRow

default Result mutateRow(RowMutations rm)
                  throws IOException

Performs multiple mutations atomically on a single row. Currently Put and Delete are supported.

Parameters:

rm - object that specifies the set of mutations to perform atomically

Returns:

results of Increment/Append operations

Throws:

IOException - if a remote or network exception occurs.

append

default Result append(Append append)
               throws IOException

Appends values to one or more columns within a single row.

This operation guaranteed atomicity to readers. Appends are done under a single row lock, so write operations to a row are synchronized, and readers are guaranteed to see this operation fully completed.

Parameters:

append - object that specifies the columns and values to be appended

Returns:

values of columns after the append operation (maybe null)

Throws:

IOException - e

increment

default Result increment(Increment increment)
                  throws IOException

Increments one or more columns within a single row.

This operation ensures atomicity to readers. Increments are done under a single row lock, so write operations to a row are synchronized, and readers are guaranteed to see this operation fully completed.

Parameters:

increment - object that specifies the columns and amounts to be used for the increment operations

Returns:

values of columns after the increment

Throws:

IOException - e

incrementColumnValue

                           throws IOException

See incrementColumnValue(byte[], byte[], byte[], long, Durability)

The Durability is defaulted to Durability.SYNC_WAL.

Parameters:

row - The row that contains the cell to increment.

family - The column family of the cell to increment.

qualifier - The column qualifier of the cell to increment.

amount - The amount to increment the cell with (or decrement, if the amount is negative).

Returns:

The new value, post increment.

Throws:

IOException - if a remote or network exception occurs.

default long incrementColumnValue(byte[] row,
                                  byte[] family,
                                  byte[] qualifier,
                                  long amount,
                                  Durability durability)
                           throws IOException

Atomically increments a column value. If the column value already exists and is not a big-endian long, this could throw an exception. If the column value does not yet exist it is initialized to amount and written to the specified column.

Setting durability to Durability.SKIP_WAL means that in a fail scenario you will lose any increments that have not been flushed.

Parameters:

row - The row that contains the cell to increment.

family - The column family of the cell to increment.

qualifier - The column qualifier of the cell to increment.

amount - The amount to increment the cell with (or decrement, if the amount is negative).

durability - The persistence guarantee for this increment.

Returns:

The new value, post increment.

Throws:

IOException - if a remote or network exception occurs.

close

default void close()
            throws IOException

Releases any resources held or pending changes in internal buffers.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Throws:

IOException - if a remote or network exception occurs.

coprocessorService

default CoprocessorRpcChannel coprocessorService(byte[] row)

Creates and returns a RpcChannel instance connected to the table region containing the specified row. The row given does not actually have to exist. Whichever region would contain the row based on start and end keys will be used. Note that the row parameter is also not passed to the coprocessor handler registered for this protocol, unless the row is separately passed as an argument in the service request. The parameter here is only used to locate the region used to handle the call.

The obtained RpcChannel instance can be used to access a published coprocessor Service using standard protobuf service invocations:

 CoprocessorRpcChannel channel = myTable.coprocessorService(rowkey);
 MyService.BlockingInterface service = MyService.newBlockingStub(channel);
 MyCallRequest request = MyCallRequest.newBuilder()
     ...
     .build();
 MyCallResponse response = service.myCall(null, request);
 

Parameters:

row - The row key used to identify the remote region location

Returns:

A CoprocessorRpcChannel instance
