方法详细资料

clone

public abstract RetryStrategy clone()

从接口复制的说明: RetryStrategy

Returns a RetryStrategy object of the same type that has not been retried.

指定者:

clone 在接口中 RetryStrategy

覆盖:

clone 在类中 Object

返回:

A RetryStrategy object of the same type that has not been retried.

getRetries

public int getRetries()

从接口复制的说明: RetryStrategy

Returns the number of retries for the current operation

指定者:

getRetries 在接口中 RetryStrategy

返回:

the number of retries for the current operation

shouldRetry

protected boolean shouldRetry(Exception ex)

A retry strategy specially used for Writer. The rules are as follows: 1. If the exception is TableStoreException and it is retryable, then a retry can be performed. 2. If the exception is ClientException (a network-related exception), then a retry can be performed. 3. If the HTTP status code is 500, 502, or 503, then a retry can be performed. 4. If the operation is a Batch operation, the batch operation can only be retried if all failed rows are retryable.

参数:

ex - Error information from the last failed access attempt; either ClientException or OTSException

返回:

nextPause

public long nextPause(String action,
                      Exception ex)

从接口复制的说明: RetryStrategy

Get the delay time before the retries-th retry is initiated. The SDK will initiate the retries-th retry after this period of time. If the return value is less than or equal to 0, it means no retry will be attempted.

指定者:

nextPause 在接口中 RetryStrategy

参数:

action - Operation name, such as "ListTable", "GetRow", "PutRow", etc.

ex - Error information from the last failed attempt, either a ClientException or a TableStoreException

返回:

The delay time before the retries-th retry is initiated (in milliseconds). A value less than or equal to 0 indicates that the operation is not retryable.
