-------------------------------
Summary: Dimensional Routed Aliases
Key: SOLR-13375
URL: https://issues.apache.org/jira/browse/SOLR-13375
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Affects Versions: master (9.0)
Reporter: Gus Heck
Assignee: Gus Heck
Current available routed aliases are restricted to a single field. This feature
will allow Solr to provide data driven collection access, creation and
management based on multiple fields in a document. The collections will be
queried and updated in a unified manner via an alias. Current routing is
restricted to the values of a single field. The particularly useful combination
at this time will be Category X Time routing but Category X Category may also
be useful. More importantly, if additional routing schemes are created in the
future (either as contributions or as custom code by users) combination among
these should be supported.
It is expected that not all combinations will be useful, and that determination
of usefulness I expect to leave up to the user. Some Routing schemes may need
to be limited to be the leaf/last routing scheme for technical reasons, though
I'm not entirely convinced of that yet. If so, a flag will be added to the
RoutedAlias interface.
Initial desire is to support two levels, though if arbitrary levels can be
supported easily that will be done.
This could also have been called CompositeRoutedAlias, but that creates a TLA
clash with CategoryRoutedAlias.
