The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for performing a backup in relation to a separated database, the method includes creating, by a processing circuit, a new backup log structured merge (LSM) tree of the separated database, wherein the new backup LSM tree is associated with a new point in time (PIT) and belongs to a group of LSM trees that comprise a primary LSM tree and one or more backup LSM trees that are associated with different PITs, and share a key value (KV) database that is mutable and is separated from the group; wherein the creating comprises storing the new backup LSM tree to a destination.”

The patent application was filed on 2023-08-14 (18/449693).

Managing LSM tree of key value pairs that is stored in NVM
Pliops Ltd., Tel Aviv, Israel, has been assigned a patent (12277340) developed by Dayan; Niv, Tel Aviv, Israel, and Twitto; Moshe, Givat Shemuel, Israel, for “managing a LSM tree of key value pairs that is stored in a non-volatile memory.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.”

The patent application was filed on 2020-10-27 (17/081975).

Pliops Ltd., Tel Aviv, Israel, has been assigned a patent (12164493) developed by Guetta; Guy, Bortnikov; Edward, Pan; Michael, Tel Aviv, Israel, Twitto; Moshe, Givat Shemuel, Israel, Weiss; Tamar, Tel Aviv, Israel, Dashevsky; Shmuel, Ramat gan, Israel, and Dayan; Niv, Tel Aviv, Israel, for a “separated database management.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for inserting a KV pair to a separated database, the method may include receiving a request to insert the KV pair to the separated database, wherein the separated database comprises a log structured merge (LSM) tree and KV database that is separated from LSM tree; determining whether the KV pair should be associated with a versioned LSM entry or with a non-versions LSM entry; and inserting the KV pair and a KV timestamp in the separated database according to the determining; wherein the inserting includes: storing a combination of the value and the KV timestamp in the KV database; defining an access key to the KV database; wherein the access key is based on the combination when determining that the KV pair should be associated with a versioned LSM; and wherein the access key is based on the key and not on the timestamp when determining that the KV pair should be associated with a non-versioned LSM.”

The patent application was filed on 2022-02-14 (17/651065).
