-------------------------------------
Summary: Use the SQL Dot Operator to access nested fields/rows
Key: SAMZA-2557
URL: https://issues.apache.org/jira/browse/SAMZA-2557
Project: Samza
Issue Type: Improvement
Components: sql
Reporter: Slim Bouguerra
After https://issues.apache.org/jira/browse/SAMZA-2507 We can use Calcite Dot
and Row operators to access nested row using a dot based path within a given
column.
Although with this new feature multiple things has to change within the
translation layer.
First We need to restructure the Query Translation Layer to allow multiple
operators between Remote Table Scan and Joins operator.
Second we have to Add a new Row Format to leverage the flat nature of the rows.
Third we need to replace legacy udfs that relies on SamzaRelRecord as base row.
