Subject [Solr Wiki] Trivial Update of "SolrCloud" by JaysonMinard
Date Wed, 13 Jan 2010 20:33:20 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "SolrCloud" page has been changed by JaysonMinard.
http://wiki.apache.org/solr/SolrCloud?action=diff&rev1=9&rev2=10

--------------------------------------------------

  
  Connection refused errors from solr_server->solr_server  (or other errors that we believe
would not result in an error if executed on a different node) should result in failover behavior
(re-request a different shard).  It can be a local policy decision to not try that node again
for a certain amount of time after so many of these errors.  Zookeeper does not need to be
updated with this info (but could be in the future).
  
- Not failures should not always fail the distributed search.  It should be configurable whether
that aborts the search or returns with a results from all non-failing nodes along with a list
of the nodes that failed.  In cases with huge document collections, a missing few percent
of total documents may not be worth stopping the user's progress; yet you would want to know
about the failure so you could indicate that the results are incomplete.

  ==== Timeouts ====
  Zookeeper ephemeral znodes can be used to determine what servers are available for requests.
