Abstract
A method for managing a log structured merged (LSM) tree of key value (KV) pairs, the LSM tree is stored in a non-volatile memory, the method may include writing a current run from a buffer to a current run location within the LSM tree, the current run comprises current KV pairs; generating or receiving current fingerprints that are indicative of the current KV pairs; performing a run writing update of a management data structure (MDS) by adding to the MDS, mappings between the current KV pairs, the current fingerprints and a current run identifier; updating the LSM tree by merging at least some runs of the LSM tree; and performing a merge update of the MDS to represent the merging.
