--------------------------------
Summary: MergeIndex could support SolrCloud operation
Key: SOLR-10560
URL: https://issues.apache.org/jira/browse/SOLR-10560
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Reporter: Mike Drob
Looking at the docs for mergeindex\[1]\[2], I don't see any equivalent
operations for SolrCloud. That it, while we can merge a single index, if we
have replicas we would need to merge into each one separately.
It would be useful to be able to be able to execute something like:
{{/admin/collections?action=mergeindexes&collection=coll1&shard=shard1&indexDir=/tmp/updatedIndex}}
Part of the problem with separate merges is that if one fails, the operator has
to manually trigger recoveries. Doing this at the collection level would let
Solr internally enforce an all-or-nothing level of success.
