SQL & SQLite compatibility

AthenaDB has its own SQL parser and executor on the encrypted engine — not a wrapper around another database.

SQLite migration path

• SQLite-compatible C API and platform shim
• athenadb-sqlite3 compatibility CLI
• Import/migration tooling

Treat this as an Early Access migration path. Compatibility phases are in the engine; GA verification is incomplete. Validate your workload rather than assuming every SQLite application runs unchanged.
