Indexing Considerations in a Clustered Environment
Although the reindexing process runs in the background, in a clustered environment this process is not distributed across the cluster. When you start a reindexing process, it is executed on the node that you are currently connected to (for example, through a load balancer).
However, the behavior of the reindexing process is propagated to all nodes in the cluster. In other words, you have access to the following regardless of which node you are connected to:
Read-only view of the database table structure on the
Indexes tab.
Reindexing status messages (progress information, or last start time, stop time, and status).
Ability to stop a running process with the
Stop Reindex button.
So, for example, if you start the reindexing process while logged in to Node A, then log out and log in later on Node B, you will still see the same information and have the same control over the process as if you were logged in to the original node.
