IdempotenceAwareRetryPolicy Class

A retry policy that avoids retrying non-idempotent statements.

In case of write timeouts this policy will always return Rethrow if the statement is considered non-idempotent (see IsIdempotent). For all other cases, this policy delegates the decision to the child policy.

Methods
  NameDescription
Public methodOnReadTimeout
Defines whether to retry and at which consistency level on a read timeout.

Note that this method may be called even if requiredResponses >= receivedResponses if dataPresent is false (see com.datastax.driver.core.exceptions.ReadTimeoutException#WasDataRetrieved).

Public methodOnRequestError
Defines whether to retry and at which consistency level on an unexpected error.

This method might be invoked in the following situations:

  1. On a client timeout, while waiting for the server response (see ReadTimeoutMillis).
  2. On a socket error (socket closed, etc.).
  3. When the contacted host replies with an OVERLOADED error or a SERVER_ERROR.

Note that when such an error occurs, there is no guarantee that the mutation has been applied server-side or not.

Public methodOnUnavailable
Defines whether to retry and at which consistency level on an unavailable exception.
Public methodOnWriteTimeout
Defines whether to retry and at which consistency level on a write timeout.
