[jira] [Created] (IGNITE-20162) Sql. Support collection types in RowSchema.

-----------------------------------------

             Summary: Sql. Support collection types in RowSchema.
                 Key: IGNITE-20162
                 URL: https://issues.apache.org/jira/browse/IGNITE-20162
             Project: Ignite
          Issue Type: Improvement
          Components: sql
    Affects Versions: 3.0.0-beta1
            Reporter: Maksim Zhuravkov


After migrating to BinaryTuple/RowSchema in sql-engine, RowSchema should be updated to support collection types such as calcite's ARRAY/MAP. These types work with array-backed rows because array-backed RowHandler is untyped.

1. Add types that describe collection types.
2. Update conversion from RelDataTypes to RowSchema types for these types.
3. Update runtime code that read/write collection types from BinaryTuple-backed rows.
