URL: https://github.com/apache/couchdb/issues/1707
 
 
   <!--- Provide a general summary of the issue in the Title above -->
   When querying a view using db.queryview api, intermittently, the api returns SocketTimeoutException: Read timed out
   ## Expected Behavior
   <!--- If you're describing a bug, tell us what should happen -->
   <!--- If you're suggesting a change/improvement, tell us how it should work -->
   In a 6 cpu/2G RAM server with ~90K documents (individual document size is small, <1k bytes),  when a view is queried, 
   the view result shall return
   ## Current Behavior
   <!--- If describing a bug, tell us what happens instead of the expected behavior -->
   <!--- If suggesting a change/improvement, explain the difference from current behavior -->
   Intermittently, the api returned SocketTimeoutException: Read timed out.
   When looked at couchdb log, we noticed a couple of logs around that time frame:
   
   1. Update index started (in some cases, for a ~90K document database, the index took more than 30 seconds)
   2. Compaction started (in some cases, compaction seems to start frequently)
