Beta release of new storage system dubbed CAIRO and new query system GRIFFIN.
CAIRO improves on now legacy system in several key areas:
- Performance. It is at least 30% faster in every test.
- Resilience. Cairo has been tested to withstand file system errors, such as corruption, space issue as well deal hardware stability issues, such as power loss or sudden reboots. Cairo will perform automatic data recovery in all of these circumstances
- Data management. Cairo implements functions of adding and removing table columns and partition management.
- Stability. Cairo is production ready. Data structures have been extensively tested to resolve all known defects.
Downsides:
- Object store and retrieval is not implemented against CAIRO. The system focus is on zero-GC embedded storage.
GRIFFIN - SQL implementation that uses CAIRO as the store.
This system is under active development. For now lacks features of legacy SQL, such as joins, group-by and analytic functions - these are not yet developed. However GRIFFIN provides sample-by implementation with various missing data fill options, including linear interpolation and more extensive language basics, such as select from function. Eventually GRIFFIN will implement all features of legacy SQL and well beyond that.
GRIFFIN also is not yet linked to HTTP server or any network service.
