mcp-duckdb-memory-server vs kglite

mcp-duckdb-memory-server: This project is an enhanced version of the MCP Knowledge Graph Memory Server, replacing its original JSON file backend with DuckDB. This upgrade significantly improves performance, scalability, and query flexibility by leveraging DuckDB's fast query processing and SQL interface.; kglite: KGLite is an embedded, Cypher-queryable knowledge graph engine for Python and Rust, designed to serve applications, analysts, and LLM agents without an external database. It offers advanced features like schema-aware descriptions for LLMs, temporal querying over historical data, and a declared ontology for data quality.
