Andrzej Bialecki created SOLR-13292:
----------------------------------------
Summary: Provide extended per-segment status of a collection
Key: SOLR-13292
URL: https://issues.apache.org/jira/browse/SOLR-13292
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: master (9.0), 8x
Reporter: Andrzej Bialecki
Assignee: Andrzej Bialecki
When changing a collection configuration or schema there may be non-obvious
conflicts between existing data and the new configuration or the newly declared
schema. A similar situation arises when upgrading Solr to a new version while
keeping the existing data.
Currently the {{SegmentsInfoRequestHandler}} provides insufficient information
to detect such conflicts. Also, there's no collection-wide command to gather
such status from all shard leaders.
This issue proposes extending the {{/admin/segments}} handler to provide more
low-level Lucene details about the segments, including potential conflicts
between existing segments' data and the current declared schema. It also adds a
new COLSTATUS collection command to report an aggregated status from all
shards, and optionally for all collections.
