so,The last two hours of the data will be in real-time node。
I try to restore the scene, When I select the last hour, or the last day of the data, it will not trigger the problem。
But when I select the last week’s data, and =groupBy queryType,
The amount of data in this datasource is about 56G，
I have 7 historical nodes that are distributed on three servers.
I found that there was a server Disappeared 1 historical node, Disappeared and 3 real-time nodes，But a few minutes later, it was restored.
Is it that my cluster configuration is not reasonable, resulting in a server pressure is too large?
You can see the situation in the annex, the history node cluster.
