I wrote a plugin for a custom JDBC datasource. This plugin registers a couple of rules.
When I ran an SQL query that uses parquet files, I found that a rule of my JDBC plugin was invoked to optimize the query ! I believe this is a mistake. Please correct me if I'm wrong. I'm saying this is a mistake because a rule registered by a plugin that utilizes a specific datasource should only be concerned about queries executed by that plugin. Query optimizations for a JDBC datasource won't probably work for queries targeted for parquet files ! What do you think ? Gelbana
