Getting "Data too long for column session_data'" creating a CACHE table

[unj1m]

Hi, I'm trying to leverage CACHE TABLE to create temporary tables that are cleaned up at the end of the session.

In creating one of these, I'm getting  Data too long for column 'session_data'.  The query I'm using isn't referencing a session_data column.

My guess is that Databricks is tracking cache tables in a session_data column somewhere.  Can anyone verify, or offer another explanation? 🙂
