Record Class ReservedStateChunk

java.lang.Object
java.lang.Record
org.elasticsearch.reservedstate.service.ReservedStateChunk
public record ReservedStateChunk(Map<String,Object> state, ReservedStateVersion metadata) extends Record
A holder for the cluster state to be saved and reserved and the version info

Apart from the cluster state we want to store and reserve, the chunk requires that you supply the version metadata. This version metadata (see ReservedStateVersion) is checked to ensure that the update is safe, and it's not unnecessarily repeated.
