> Allow hybrid model in the Row set-based scan framework
> ------------------------------------------------------
>
> Key: DRILL-7011
> URL: https://issues.apache.org/jira/browse/DRILL-7011
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.15.0
> Reporter: Arina Ielchiieva
> Assignee: Paul Rogers
> Priority: Major
> Fix For: 1.16.0
>
>
> 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.
