Method Details

setOperationTimeout

public AsyncTableBuilderBase<C> setOperationTimeout(long timeout,
 TimeUnit unit)

Description copied from interface: AsyncTableBuilder

Set timeout for a whole operation such as get, put or delete. Notice that scan will not be effected by this value, see scanTimeoutNs.

Operation timeout and max attempt times(or max retry times) are both limitations for retrying, we will stop retrying when we reach any of the limitations.

Specified by:

setOperationTimeout in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

See Also:

• AsyncTableBuilder.setMaxAttempts(int)
• AsyncTableBuilder.setMaxRetries(int)
• AsyncTableBuilder.setScanTimeout(long, TimeUnit)

setScanTimeout

public AsyncTableBuilderBase<C> setScanTimeout(long timeout,
 TimeUnit unit)

Description copied from interface: AsyncTableBuilder

As now we have heartbeat support for scan, ideally a scan will never timeout unless the RS is crash. The RS will always return something before the rpc timed out or scan timed out to tell the client that it is still alive. The scan timeout is used as operation timeout for every operation in a scan, such as openScanner or next.

Specified by:

setScanTimeout in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

See Also:

• AsyncTableBuilder.setScanTimeout(long, TimeUnit)

setRpcTimeout

public AsyncTableBuilderBase<C> setRpcTimeout(long timeout,
 TimeUnit unit)

Description copied from interface: AsyncTableBuilder

Set timeout for each rpc request.

Notice that this will NOT change the rpc timeout for read(get, scan) request and write request(put, delete).

Specified by:

setRpcTimeout in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

setReadRpcTimeout

public AsyncTableBuilderBase<C> setReadRpcTimeout(long timeout,
 TimeUnit unit)

Description copied from interface: AsyncTableBuilder

Set timeout for each read(get, scan) rpc request.

Specified by:

setReadRpcTimeout in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

setWriteRpcTimeout

public AsyncTableBuilderBase<C> setWriteRpcTimeout(long timeout,
 TimeUnit unit)

Description copied from interface: AsyncTableBuilder

Set timeout for each write(put, delete) rpc request.

Specified by:

setWriteRpcTimeout in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

setRetryPause

public AsyncTableBuilderBase<C> setRetryPause(long pause,
 TimeUnit unit)

Description copied from interface: AsyncTableBuilder

Set the base pause time for retrying. We use an exponential policy to generate sleep time when retrying.

Specified by:

setRetryPause in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

See Also:

• AsyncTableBuilder.setRetryPauseForServerOverloaded(long, TimeUnit)

setRetryPauseForServerOverloaded

public AsyncTableBuilderBase<C> setRetryPauseForServerOverloaded(long pause,
 TimeUnit unit)

Description copied from interface: AsyncTableBuilder

Set the base pause time for retrying when HBaseServerException.isServerOverloaded(). We use an exponential policy to generate sleep time when retrying.

This value should be greater than the normal pause value which could be set with the above AsyncTableBuilder.setRetryPause(long, TimeUnit) method, as usually HBaseServerException.isServerOverloaded() means the server is overloaded. We just use the normal pause value for HBaseServerException.isServerOverloaded() if here you specify a smaller value.

Specified by:

setRetryPauseForServerOverloaded in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

See Also:

• AsyncTableBuilder.setRetryPause(long, TimeUnit)

setMaxAttempts

public AsyncTableBuilderBase<C> setMaxAttempts(int maxAttempts)

Description copied from interface: AsyncTableBuilder

Set the max attempt times for an operation. Usually it is the max retry times plus 1. Operation timeout and max attempt times(or max retry times) are both limitations for retrying, we will stop retrying when we reach any of the limitations.

Specified by:

setMaxAttempts in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

See Also:

• AsyncTableBuilder.setMaxRetries(int)
• AsyncTableBuilder.setOperationTimeout(long, TimeUnit)

setStartLogErrorsCnt

public AsyncTableBuilderBase<C> setStartLogErrorsCnt(int startLogErrorsCnt)

Description copied from interface: AsyncTableBuilder

Set the number of retries that are allowed before we start to log.

Specified by:

setStartLogErrorsCnt in interface AsyncTableBuilder<C extends ScanResultConsumerBase>

setRequestAttribute

public AsyncTableBuilder<C> setRequestAttribute(String key,
 byte[] value)

Description copied from interface: AsyncTableBuilder

Set a request attribute

Specified by:

setRequestAttribute in interface AsyncTableBuilder<C extends ScanResultConsumerBase>
