Class KVClient

Compact compacts the event history in the etcd key-value store. The key-value store should be periodically compacted or the event history will continue to grow indefinitely.

DeleteRange deletes the given range from the key-value store. A delete request increments the revision of the key-value store and generates a delete event in the event history for every deleted key.

Put puts the given key into the key-value store. A put request increments the revision of the key-value store and generates one event in the event history.

Range gets the keys in the range from the key-value store.

RangeStream gets the keys in the range from the key-value store.

This RPC is intentionally gRPC-only and does not provide a grpc-gateway REST mapping, because streaming chunked responses are not a good fit for standard JSON/REST semantics.

Txn processes multiple requests in a single transaction. A txn request increments the revision of the key-value store and generates events with the same revision for every completed request. It is not allowed to modify the same key several times within one txn.
