Enum tikv::storage::txn::commands::ResponsePolicy

pub enum ResponsePolicy {
    OnApplied,
    OnCommitted,
    OnProposed,
}

Represents for a scheduler command, when should the response sent to the client. For most cases, the response should be sent after the result being successfully applied to the storage (if needed). But in some special cases, some optimizations allows the response to be returned at an earlier phase.

Note that this doesn’t affect latch releasing. The latch and the memory lock (if any) are always released after applying, regardless of when the response is sent.

Variants

OnApplied

Return the response to the client when the command has finished applying.

OnCommitted

Return the response after finishing Raft committing.

OnProposed

Return the response after finishing raft proposing.
