Optional: Defaults to true

LeaderLease time, if leader doesn’t update its TTL in etcd after lease time, etcd will expire the leader key and other servers can campaign the leader again. Etcd only supports seconds TTL, so here is second too. Optional: Defaults to 3

Log related config.

Backward compatibility.

TsoSaveInterval is the interval to save timestamp. Optional: Defaults to 3s

QuotaBackendBytes Raise alarms when backend size exceeds the given quota. 0 means use the default quota. the default size is 2GB, the maximum is 8GB.

AutoCompactionMode is either ‘periodic’ or ‘revision’. The default value is ‘periodic’.

AutoCompactionRetention is either duration string with time unit (e.g. ‘5m’ for 5-minute), or revision unit (e.g. ‘5000’). If no time unit is provided and compaction mode is ‘periodic’, the unit defaults to hour. For example, ‘5’ translates into 5-hour. The default retention is 1 hour. Before etcd v3.3.x, the type of retention is int. We add ‘v2’ suffix to make it backward compatible.

TickInterval is the interval for etcd Raft tick.

ElectionInterval is the interval for etcd Raft election.

Prevote is true to enable Raft Pre-Vote. If enabled, Raft runs an additional election phase to check whether it would get enough votes to win an election, thus minimizing disruptions. Optional: Defaults to true

NamespaceClassifier is for classifying stores/regions into different namespaces. Optional: Defaults to true
