Drill - Metadata Cache

Question asked by john.humphreys on Jan 25, 2018

When you cache the metadata for a file in Drill like this:

 

REFRESH TABLE METADATA dfs.`/path/file.parquet`

 

does it apply to the current connection, or to the actual drill-bits themselves (i.e. across all connections)?

 

I'd like to replace parquet files/tables with newer versions that may have different schemas and I'm wondering if that would confuse drill as it had cached old metadata in existing connections.
