Arina Ielchiieva updated DRILL-7011:
------------------------------------
Description:
As part of schema provisioning project we want to allow hybrid model for Row
set-based scan framework, namely to allow to pass custom schema metadata which
can be partial.
Currently schema provisioning has SchemaContainer class that contains the
following information (can be obtained from metastore, schema file, table
function):
1. schema represented by org.apache.drill.exec.record.metadata.TupleMetadata
2. properties represented by Map<String, String>, can contain information if
schema is strict or partial (default is partial) etc.
