-----------------------------------
[~NIzhikov] [~stuartmacd] I have gone through the implementation of supporting
schema name Ignite Spark SQL and it's only having support to schema name to
read data, not for write. Any specific reason for the same? Is it in the future
roadmap?
> Spark SQL Table Schema Specification

> Key: IGNITE-9228
> URL: https://issues.apache.org/jira/browse/IGNITE-9228
> Project: Ignite
> Issue Type: Improvement
> Components: spark
> Affects Versions: 2.6
> Reporter: Stuart Macdonald
> Assignee: Stuart Macdonald
> Priority: Major
> Fix For: 2.8
>
>
> The Ignite Spark SQL interface currently takes just “table name” as a
> parameter which it uses to supply a Spark dataset with data from the
> underlying Ignite SQL table with that name.
> To do this it loops through each cache and finds the first one with the
> given table name [1]. This causes issues if there are multiple tables
> registered in different schema with the same table name as you can only
> access one of those from Spark. We could either:
> 1. Pass an extra parameter through the Ignite Spark data source which
> optionally specifies the schema name.
> 2. Support namespacing in the existing table name parameter, ie
> “schemaName.tableName”
