httk-store

Status: Early beta

⚠️ EARLY BETA

This is an early beta release of httk₂. The organization of the packages and their APIs should not yet be regarded as stable, and may change between releases.

httk-store is a httk₂ module for data management. Built on the stdlib-only contracts and models in httk-core, it provides in-memory httk.core.EntryProvider implementations for the standard OPTIMADE entry types (references, files, calculations), property-definition validation on jsonschema, and a database storage layer that stores plain frozen dataclasses in SQLite, DuckDB, PostgreSQL, or MongoDB, makes them queryable through a backend-agnostic search DSL, and serves them through the entry-provider contract. ClickHouse supports bulk ingestion and read serving with its documented write restrictions.

Install the optional backend you need with httk-store[db] (SQLite), httk-store[duckdb], httk-store[postgresql], httk-store[mongodb], or httk-store[clickhouse,parallel]. See the storage documentation for backend capabilities and deployment requirements.
