Creating a snapshot of indexes when adding a node

Nik Stas

 

Hi team

When a new node is added to the cluster, a snapshot of indexes is created on the main node and restored on the second node. First, I copy the indexes to the second node. I know that there is such a problem and it seems to have been fixed in 9.4. I have tried many options and hypotheses. I want to understand how others solve this problem.

 

The problem for me is that I have 50k+ active users and 30GB of indexes.

Solution. Enable automatic snapshot creation on a schedule. After creating a snapshot, new nodes will be restored from the snapshot without affecting the first node.
