Hi, i need more deep explanation the difference between phase on ILM.
In documentation it is said:
hot : The index is actively being written to warm: The index is generally not being written to, but is still queried cold: The index is no longer being updated and is seldom queried. The information still needs to be searchable, but it’s okay if those queries are slower.
But there is no explanation what make it become slower or fast between phase. What happened in the background when indices move from one phase to another. And as far as I know, logs only written to the newest indices, right? Let say, I have 2 indices:
mylogs-2020-03-09 and mylogs-2020-03-08. It will write to indices mylogs-2020-03-09 even I didnt enable ILM?
