Hi, Storage plugin needs to be enhanced to handle the indexing capabilities for the corresponding storage engines. Indexing is supported by some of the databases like MongoDB, MapRDB etc. Currently, Drill's MapRDB storage plugin is enhanced to support the indexing mechanisms for MapRDB. If you are using any other storage engine then the corresponding storage plugin needs to be enhanced in the similar lines. The indexing API is nicely abstracted out so as to easily integrate other storage engines which support indexing mechanisms.
Please let us know the storage engine you are trying to use? Hope this helps.
