Methods
| AtomicGroupCommitAsync(Int64, Int64, CancellationToken) |
Commits a particular atomic group. |
| AtomicGroupRollbackAsync(Int64, Int64, CancellationToken) |
Rolls back a particular atomic group. |
| AtomicGroupUndoProgressAsync(Int64, CancellationToken) |
Indicates that progress beyond a particular commit sequence number that is provided via AtomicGroupCommitAsync(Int64, Int64, CancellationToken) should be undone. |
| GetCopyContext() |
Obtains context on a secondary replica after it is created and opened to send context to the primary replica. (Inherited from IStateProvider) |
| GetCopyState(Int64, IOperationDataStream) |
Obtains state on a primary replica that is required to build a secondary replica. (Inherited from IStateProvider) |
| GetLastCommittedSequenceNumber() |
Obtains the last sequence number that the service has committed, also known as Logical Sequence Number (LSN). (Inherited from IStateProvider) |
| OnDataLossAsync(CancellationToken) |
Indicates that a write quorum of replicas in this replica set has been lost, and that therefore data loss might have occurred. The replica set consists of a majority of replicas, which includes the primary replica. (Inherited from IStateProvider) |
| UpdateEpochAsync(Epoch, Int64, CancellationToken) |
Indicates to a replica that the configuration of a replica set has changed due to a change or attempted change to the primary replica. The change occurs due to failure or load balancing of the previous primary replica. Epoch changes act as a barrier by segmenting operations into the exact configuration periods in which they were sent by a specific primary replica. (Inherited from IStateProvider) |
