Class and Description |
---|
Idempotent
Used to mark certain methods of an interface as being idempotent, and
therefore warrant being retried on failover.
|
Class and Description |
---|
FailoverProxyProvider
An implementer of this interface is capable of providing proxy objects for
use in IPC communication, and potentially modifying these objects or creating
entirely new ones in the event of certain types of failures.
|
Class and Description |
---|
AtMostOnce
Used to mark certain methods of an interface with at-most-once semantics.
|
Idempotent

RetryInvocationHandler
This class implements RpcInvocationHandler and supports retry on the client
side.
|
RetryPolicies.MultipleLinearRandomRetry
Given pairs of number of retries and sleep time (n0, t0), (n1, t1), ...,
the first n0 retries sleep t0 milliseconds on average,
the following n1 retries sleep t1 milliseconds on average, and so on.
|
RetryPolicies.MultipleLinearRandomRetry.Pair
Pairs of numRetries and sleepSeconds
