Abstract
There may be provided, systems, method and non-transitory computer readable media for accessing a key value pair stored in a solid state drive (SSD) memory, the method may include calculating, by a SSD memory controller and based on an input key, a first bucket identifier and a first inter-bucket value; determining a block cluster that stores the key pair value, based on the first bucket identifier, the first inter-bucket value and first metadata of a first data structure; calculating, based on the input key, a second bucket identifier and a second inter-bucket value; determining at least one of a key pair value retrieval information and a representative key pair value retrieval information, based on the second bucket identifier, the second inter-bucket value and second metadata of a second data structure; wherein the second data structure is allocated to the block cluster; wherein the second metadata comprises second logical slots, a second slot locator and second collision separation metadata; wherein at least the second slot locator comprise metadata only on representative key-pair values that are a subset of multiple key-pair values stored in the block cluster; and retrieving a…
