K4 is an open-source, transactional, and durable embedded storage engine based on a Log-Structured Merge (LSM) tree architecture. It supports a key-value data model with variable-length binary keys and values, write-ahead logging for durability, atomic transactions, and configurable background compaction. The system provides a custom API for operations such as Get, Put, Delete, and range queries, and includes a C library for foreign function interface integration.
