paul-rogers commented on issue #2060: DRILL-7706: Implement Drill RDBMS Metastore URL: https://github.com/apache/drill/pull/2060#issuecomment-615394559 @arina-ielchiieva, this is great! I wonder, will this PR handle a particular use case that I'm seeing? The metastore works for files. We are seeing more cases where users want to read other data sources: HTTP, Mongo, whatever. These sources deliver JSON, which can be ambiguous. We want to use a provided schema to resolve ambiguities. (That work is ongoing in updating the JSON reader, etc.) So, we need a place to store the provided schema. Recall that, for files, we put the provided schema in the same folder as the data. For the HTTP plugin, say, there is no directory to place the files. So, can we use the DB-backed metastore? Will there be a standard way for a plugin to map its concept of a table to an entry in the metastore which can hold the provided schema?
