DuckDB
DuckDB
DuckDB is an in-process SQL OLAP database management system.
As an in-process database, DuckDB is easy to configure: specify the path to your DuckDB filename as the database name, e.g. <PATH_TO_YOUR_DUCKDB_FILE>/duckdb.
One thing to remember is about how DuckDB manages concurrency. The things to remember are summarized below:
Only one process at a time can both read and write to the database.
Multiple processes can read from the database, but no processes can write. To set this behavior, remember to specify in the connection’s options the property duckdb.read_only = true
For details, please refer to DuckDB Java API documentation.
