    Abstract: Data storage system and method for managing transaction requests to the data storage system utilizes a write ahead log to write transaction requests received at the data storage system during a current checkpoint generation. After the transaction requests in the write ahead log are applied to a copy-on-write (COW) storage data structure stored in a storage system, one of first and second allocation bitmaps is updated to reflect changes in the COW storage data structure with respect to allocation of storage space in the storage system, and one of first and second super blocks is updated with references to central nodes of the COW storage data structure. After the allocation bitmap and the super block have been updated, an end indicator for the current checkpoint generation is written in the write ahead log to indicate that processing of the transaction requests for the current checkpoint generation has been completed.

    Abstract: Embodiments of the present disclosure relate to techniques for performing a merge update for a database. In particular, certain embodiments of a method include generating a message comprising a first key and a first transaction associated with the first key, the first transaction indicating a transaction to perform other than for key-value pairs comprising the first key. The method further includes storing the message in a database. The method further includes merging the message with a first key-value pair stored in the database, the first-key value pair comprising the first key. The method further includes performing the first transaction based on merging the message with the first key-value pair.
