service KV (etcdserver/etcdserverpb/rpc.proto)
Method Request Type Response Type Description
Range RangeRequest RangeResponse Range gets the keys in the range from the key-value store.
Put PutRequest PutResponse 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.

message TxnRequest (etcdserver/etcdserverpb/rpc.proto)

From google paxosdb paper: Our implementation hinges around a powerful primitive which we call MultiOp. All other database operations except for iteration are implemented as a single call to MultiOp. A MultiOp is applied atomically and consists of three components: 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check for the absence or presence of a value, or compare with a given value. Two different tests in the guard may apply to the same or different entries in the database. All tests in the guard are applied and MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise it executes f op (see item 3 below). 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or lookup operation, and applies to a single database entry. Two different operations in the list may apply to the same or different entries in the database. These operations are executed if guard evaluates to true. 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.

Field Description Type
header   ResponseHeader
watch_id watch_id is the ID of the watcher that corresponds to the response. int64

canceled canceled is set to true if the response is for a cancel watch request. No further events will be sent to the canceled watcher. bool
compact_revision compact_revision is set to the minimum index if a watcher tries to watch at a compacted index. This happens when creating a watcher at a compacted revision or the watcher cannot catch up with the progress of the key-value store. The client should treat the watcher as canceled and should not try to create any watcher with the same start_revision again. int64
cancel_reason cancel_reason indicates the reason for canceling the watcher. string
