Kyoto TreeDB is the database type in Kyoto Cabinet, FAL Labs' embedded key-value database library, that stores data in a file using a B+ tree structure. Unlike the hash-based HashDB, keys are stored in sorted order, so range searches and cursor traversal are possible, and because records are grouped and compressed per page, it is space-efficient when there are many small records. It is identified by the file extension .kct and is the successor to Tokyo Cabinet.
