This PR changes the name of the state index from
.ml-stateto.ml-state-000001so that the rollover can be performed on the index.The state index pattern (
.ml-state*) is still valid as it "catches" both legacy and new name.If the user already has the legacy state index (
.ml-state), we will not create the new one (.ml-state-000001).This PR doesn't create any ILM policy nor does it invoke the rollover action. It can be viewed as a prerequisite for implementing either ILM or rollover.
