[jira] [Created] (BEAM-4815) [SQL] Document/fix text table (TextIO) insert behavior

Anton Kedin created BEAM-4815:
---------------------------------

             Summary: [SQL] Document/fix text table (TextIO) insert behavior
                 Key: BEAM-4815
                 URL: https://issues.apache.org/jira/browse/BEAM-4815
             Project: Beam
          Issue Type: Improvement
          Components: dsl-sql
            Reporter: Anton Kedin


Tables of type `text` are backed by TextIO. We don't do any extra configuration, so it results in behavior like this:

 - create text table with location 'test-file.csv'

 - if the file exists, you can select from it;

 - now insert values into that table;

     - this results in TextIO writing files with names like 'test-file.csv-00000-of-00001';

     - selecting from the original table doesn't allow selecting from the newly created files;

We need to properly document this, possibly log to Stdout.
