Docs: View Operation in Cluster - Overhaul

    Details

      Description

      There is an image on this page:

      http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-views-operation-cluster.html

      The drawing doesn't make sense to me. The colors show that 3 nodes have local results, and 2 nodes have remote results. I'm not sure what that means. As I understand it, the client will connect to one of the nodes. Only that node will be "local" results, all other nodes will be remote.

      Maybe I misunderstand the point of the picture, in which case the explaining text probably should be improved.

      =============

      Image of Remote/Local View Results doesn't make sense

      Introduces idea of Remote and Local Results and does not explain, or define.

      Tim: thinks local are results at node that receives a query and remote are all the parts of a result set that live at other nodes.

      =========

      Very confusing:

      -Too many bullet point and no content to tie points together
      -Passive tense
      -Talks about full or eventual consistency without explaining what it means
      -Talks about consistent views, without explaining

      ===============

      Suggestions:

      Group discusion into

      -Query time within cluster - data spread out and request coordinated with peer nodes by node that recieves query.

      -Replication of indexes

      -During rebalance: leverage existing content in 2.0 release note explaining "consistent query results on rebalance" which means you get the same results on rebalance as if no rebalance occurring.

      -Introduce idea of partial results = when a node down
      -Introduce enabling indexing of replicate data as an option (but costly too)

      No reviews matched the request. Check your Options in the drop-down menu of this sections header.
