python - Accessing RedShift Table inside UDF -

-

i have 2 tables:

  1. main table
  2. rules reference table(if, else if, else)

i cannot join tables directly because reference tables contains if,else if condition data.

same functionality have implemented using distributed cache udf in hive , want same behavior in redshfit also.

i want apply reference rules table each , every main table rows.

whether can access entire reference table inside udf?

currently it's impossible access underlining db udf on redshift, not supported yet.
