const (
	// StatusGreen means that all shards are allocated.
	StatusGreen = "green"
	// StatusYellow means that the primary shard is allocated but replicas are not.
	StatusYellow = "yellow"

	StatusRed = "red"
)

The index level status is controlled by the worst shard status. The cluster status is controlled by the worst index status. On the shard level:

const ESVersion = "7.16.1"

ESVersion represents the tatris-compatible elasticsearch version, and some elsticsearch client tools need to obtain the elasticsearch version
