Query execution engine for LLKV.

This crate provides the query execution layer that sits between the query planner (llkv-plan) and the storage layer (llkv-table, llkv-column-map).

Module Organization

• translation: Expression and projection translation utilities
• types: Core type definitions (tables, schemas, columns)
• insert: INSERT operation support (value coercion)

The QueryExecutor and SelectExecution implementations are defined inline in this module for now, but should be extracted to a dedicated query module in a future refactoring.

LLKV Executor

llkv-executor evaluates SELECT plans for the LLKV database toolkit. It produces streaming Arrow RecordBatches, coordinating with table scans, joins, and aggregation primitives while remaining oblivious to transaction orchestration.

This crate is not intended for direct standalone use.
