DecorrJitter increases the maximum jitter based on the last random value.

EqualJitter is also randomized, but prevents very short sleeps.

FullJitter applies random factors to strict exponential.

Maximum total sleep time(in ms) for kv/cop commands.

Maximum total sleep time(in ms) for kv/cop commands.

Safe point constants.

This is almost the same as 'tikv_gc_safe_point' in the table 'mysql.tidb', save this to pd instead of tikv, because we can't use interface of table if the safepoint on tidb is expired.

Timeout durations.

NoJitter makes the backoff sequence strict exponential.

For requests that may need scan region multiple times.

For requests that may need scan region.

ResolvedCacheSize is max number of cached txn status.

Timeout durations.

CommitMaxBackoff is max sleep time of the 'commit' command.

ErrBodyMissing response body is missing error.

MySQL error instances.

ErrMaxScanLimitExceeded is returned when the limit for rawkv Scan is to large.

MySQL error instances.

GrpcKeepAliveTime is the duration of time after which if the client doesn't see any activity it pings the server to see if the transport is still alive.

GrpcKeepAliveTimeout is the duration of time for which the client waits after having pinged for keepalive check and if no activity is seen even after that the connection is closed.

MaxCallMsgSize set max gRPC receive message size received from server.

MaxConnectionCount is the max gRPC connections that will be established with each tikv-server.

MaxRawKVScanLimit is the maximum scan limit for rawkv Scan.
