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)
• utils: Utility functions (time)

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.

utils

Utility functions for the executor.

Structs

QueryExecutor

Query executor that executes SELECT plans.

QueryLogGuard

Guard object that pops the current query label when dropped.

SelectExecution

Streaming execution handle for SELECT queries.

Functions

current_query_label
