Tableau: Add ability to force parsing of Custom SQL

[alexs-101]

Tableau is not good at parsing of custom SQL queries even those that are marked as supported, so if we build table/column level linage blindly relying on metadata returned by Tableau server, the resulting linage graph is far from what is expected:

• aliases instead of real table names
• no column linages
• ragged linage

Experiments with sqlglot based parser of SQL queries used by DataHub gives much better results. But the problem is it is used only for cases when Tableau was unable to parse Custom SQL query on its own and did not return upstream tables metadata.

Could you implement an option allowing to force parsing of Custom SQL queries and ignoring upstream tables metadata provided by Tableau?

The fix is by the link:
#9838

See the feature
force_extraction_of_lineage_from_custom_sql_queries: true | false
