   It's probably because the view shard is processing the purge requests and has to catch up. Processing a lot of purge requests is about same as the making a lot of db updates and waiting for the view to catch up. 
   
   Partition could be located on the same shard as the other partitions and views are built per-shard. So, if the shard hasn't caught up yet, it will block clients waiting the latest updates from the partitions on that shard. One way to handle it could be to [split he shard range](https://docs.couchdb.org/en/3.2.2-docs/cluster/sharding.html#splitting-shards) to hopefully isolate the partition to just one shard.
