Details

    Description

      Steps taken to hit the issue

      1. Created a 3 node kv cluster
      2. Created a magma bucket with 3 collections 
      3. Added 10M docs to each collection - dims 4096 vector
      4. Added 5 fts nodes
      5. Created 1 index for each collection
      6. Failed over one of the fts nodes
      7. Added it back to the cluster after a while during indexing
      8. The CPU utilization was 100% during this time and the rebalance was stuck at 5.9%.
      9. The rebalance was hung for 30+ minutes.
      10. Stopped the rebalance since there was no progress. The indexing was also very slow.
      11. Post this the cpu percentage never came down. The indexing rate was still very slow.
      12. Dropped all the indexes.
      13. The cpu percent is 100% even after 30-40 minutes post index drop.
