Crate llkv_executor 

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.

Functions

current_query_label

Fetch the innermost query label associated with the current execution thread.

current_time_micros
