------------------------------------
Summary: Clearly document the limit for the maximum number of
documents in a single index
Key: SOLR-3504
URL: https://issues.apache.org/jira/browse/SOLR-3504
Project: Solr
Issue Type: Improvement
Components: update
Affects Versions: 3.6
Reporter: Jack Krupansky
Priority: Minor
Although the actual limit to the number of documents supported by a Solr
implementation depends on the number of shards, unless the user is intimately
familiar with the implementation of Lucene, they may not realize that a single
Solr index (single shard, single core) is limited to approximately 2.14 billion
documents regardless of their processing power or memory. This limit should be
clearly documented for the Solr user.
Granted, users should be strongly discouraged from attempting to create a
single, unsharded index of that size, but they certainly should have to find
out about the Lucene limit by accident.
A subsequent issue will recommend that Solr detect and appropriately report to
the user when and if this limit is hit.
