We want to use https://calcite.apache.org/ to take a high-level SQL query that is written against a metadata schema and translate that into the actual PostgreSQL query. From the design doc, we want to take something like this ```sql SELECT * FROM smilesdb WHERE created_date > '2020-01-01' AND absorb < 300.0 ORDER BY created_date desc LIMIT 10; ``` and transform it into this ```sql SELECT dp.* FROM data_product dp INNER JOIN data_product_metadata_schema dpms ON dp.data_product_id = dpms.data_product_id INNER JOIN metadata_schema ms ON ms.metadata_schema_id = dpms.metadata_schema_id WHERE nullif(metadata ->> 'absorb', '') :: float < 300.0 AND created_date > '2020-01-01' AND ms.schema_name = 'smilesdb'; ``` Note: the query above is missing an authorization where clause, but I think for the initial investigation being able to produce the above query will be sufficient. -- This is an automated message from the Apache Git Service.
