WebbWe implemented consistent hash-based routing to our data services to enable more effective coalescing. For each request to our data service, we provide a routing key. For messages, this is a channel ID, so all requests for the same channel go to the same instance of the service. This routing further helps reduce the load on our database. recycling candles to make other candlesWebbIf the shard key modification does not result in moving the document to another shard, you can specify multiple shard key modification in the bulk operation.
