libzdb is a lightweight embedded database:
- Data is organized into tables and rows; tables have a strict schema
- Column-oriented internal storage layout for efficient compression and I/O
- Allows reading data without copying it (zero-copy)
- Supports non-blocking I/O via io_submit/aio
- Implemented as a lightweight C/C++ library
- Safe to use from multiple threads and processes
To build and install libzdb from a distribution tarball or git checkout, run these commands:
$ cmake . $ make $ sudo make install
To run the test suite:
$ make test
You can find the full documentation and screenshots of example programs at https://libzdb.org/
