Maksim Timonin created IGNITE-15391:
---------------------------------------
Summary: IndexQuery should be created with a list of fields only
Key: IGNITE-15391
URL: https://issues.apache.org/jira/browse/IGNITE-15391
Project: Ignite
Issue Type: New Feature
Reporter: Maksim Timonin
Assignee: Maksim Timonin
I believe that it's a useful feature. My main argument is still the same:
1. Ignite provides to users the possibility to create an index without name
setting. Then Ignite should provide the possibility to query them.
2. Naming of index isn't transparent, and hidden in internal packages. For
example QuerySqlField provides opportunity to create an index, and set name to
field (but not for index).
3. There is an example of using such API in other databases: as Ivan mentioned,
MongoDB doesn't require to specify an index name [1], it searches it by fields
only. Note, MongoDB doesn't require strict fields order for querying indexes,
but requires it for sorting [2].
I don't see reasons not to provide a similar API for our users. Agree, that
order of fields is under discussion.
