Shalin Shekhar Mangar commented on SOLR-2595: --------------------------------------------- Example: Lets say you have a core C1 on host H1 which you want to split and move a part of the index to core C2 on host H2 The sequence of operation can be: # Use SOLR-2593 to split C1 and move the part to be migrated into a temporary core, say "S" # Create a temporary core on H2 host, say "T" # Assign "T" to be a slave of "S" # When replication completes, use SOLR-2596 to merge "T" into "C2" - perhaps update some ZK flags so that Some details still need to be figured out e.g. * What strategy to use for splitting? * How to delete the migrated part from the source index? * How to update the shard lookup and distributed indexing schemes for the migrated part? * What happens to writes during the migration? Should we disallow it? > Split and migrate indexes > ------------------------- > > Key: SOLR-2595 > URL: https://issues.apache.org/jira/browse/SOLR-2595 > Project: Solr > Issue Type: New Feature > Components: multicore, replication (java), SolrCloud > Reporter: Shalin Shekhar Mangar > Fix For: 4.0 > > > When an shard's index grows too large or a shard becomes too loaded, it > should be possible to split parts of a shard's index and migrate/merge to a > less loaded node. -- This message is automatically generated by JIRA.
