app/cluster: communicate node IDs when performing a handshake 
Send a node ID of vmstorage as a part of vmselect and vminsert handshakes.
Use vmstorage node ID as an identifier for consistent hashing at vminsert.

Cluster native endpoints calculate vminsert and vmselect node IDs as a hash of all underlying storage node IDs, so that it will also remain consistent in case of address changes.

README.md

vmselect performs the following tasks:

  • Splits incoming selects to tasks for vmstorage nodes and issues these tasks to all the vmstorage nodes in the cluster.

  • Merges responses from all the vmstorage nodes and returns a single response.

The vmui directory contains static contents built from app/vmui package with make vmui-update command. The vmui page is available at http://<vmselect>:8481/select/<accountID>/vmui/.
