> Key: IGNITE-17684
> URL: https://issues.apache.org/jira/browse/IGNITE-17684
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Yury Gerzhedovich
> Priority: Major
> Labels: ignite-3, tech-debt
>
> Right now internaly we use array of objects to represent row in SQL instead
> of BinaryTuple and do unnecessary convertation.
> Let's investigate possibility migration from array of objects to direct usage
> of BinaryTuple in execution tree. There are possible issue for some type
> execution, like a twophase aggregates and potentialy we should use different
> representation of row for different parts.
> Start points are:
> org.apache.ignite.internal.sql.engine.exec.ArrayRowHandler
> org.apache.ignite.internal.sql.engine.schema.IgniteTableImpl#toRow
> As result of the task - list of issues which need to be resolved to implement
> reuse BinaryTuple
