| Description |
|
Currently during a granularity update, mongos and shards may see inconsistent granularity values. This causes read / write operations routed to wrong shards, and we need to have a consistent value for granularity during the update. The value will be stored on the config server, and read / write operations will be blocked temporarily during its update and use the config server value as the source of truth. See this document for more detailed discussion https://docs.google.com/document/d/1ljVx7gni5dg6vuLSL2li14lq13T2RqENWEGKKeliCzw/edit#heading=h.948j6cnha6ak. |
