FAQs

What programming languages does nutsdb support?

nutsdb is written in pure Go and is designed to be used within Go applications. Its API and documentation are tailored for Go developers, making it a native solution for projects built with the Go language.

How does nutsdb ensure data consistency?

nutsdb ensures data consistency through its support for fully serializable transactions. All database operations occur within a transaction (Tx), which can be read-only or read-write, guaranteeing atomic commits and rollbacks for reliable data management.

What are the benefits of Merge V2 and HintFile features?

Merge V2 significantly improves compaction performance and reduces memory usage by approximately 65% for large datasets. HintFile dramatically cuts database startup times by persisting indexes, eliminating the need for full data file scans during recovery, and offers automatic fallback if hint files are missing.
