It depends. When you have no replica allocated (default with only one node), then replica is first copied over the network and then transaction log is replayed for remaining operations. When the replica is allocated, each operation (transaction log) is replayed on each replica.
About terminology, we don't speak about "replica nodes" but "replica shards". Index is split into shards. Shards are allocated on nodes. A shard can be a primary or a replica. So on a given node, you can have primary shards or replica shards. It does not really matter. Makes sense? -- David Pilato | Technical Advocate | Elasticsearch.com @dadoonet | @elasticsearchfr Le 15 janvier 2014 at 16:54:59, Gianluca Bassini ([email protected]) a écrit: I'm curious about elasticsearch cluster architecture and I didn't find any documentation about it. In particulary I'm interested about how replica nodes works, replica node receive operation log from master and performe the same operation (like in mongodb replica set) or the replica copy the delta chunk from the master like solr Thanks in advance Gianluca -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
