Subject What gets written to the other shards?
Date Mon, 12 Aug 2013 22:50:18 GMT
Hello,  I am trying to set a four shard system for the first time.  I do
not understand why all the shards data are growing at about the same rate
when I push the documents to only one shard.

The four shards represent four calendar years.  And for now, on a
development machine, these four shards run on four different ports.

The first shard is started with Zookeeper.

The log of the other shards is filed with something like:

7882051 [qtp1154079020-1245] INFO
org.apache.solr.update.processor.LogUpdateProcessor – [collection1]
webapp=/solr path=/update params={distrib.from=
{add=[14939-96467-304 (1443204912169091072), 14939-96467-308
(1443204912179576832), 14939-96467-310 (1443204912185868288),
14939-96467-311 (1443204912192159744), 14939-96467-313
(1443204912204742656), 14939-96467-314 (1443204912220471296),
14939-96467-318 (1443204912239345664), 14939-96467-319
(1443204912250880000), 14939-96467-322 (1443204912257171456),
14939-96467-324 (1443204912263462912)]} 0 282

What is getting written to the other shards? Is a separate index computed
on all four shards?  I thought that when pushing a document to one shard,
only that shard would update its index.
