Abstract: A system and method for updating a configuration of a host system so that the memory sub-system of the host system emulates performance characteristics of a target memory sub-system. An example system includes a memory sub-system; and a processor, operatively coupled with the memory sub-system, to perform operations comprising receiving a request to emulate a characteristic of a target memory sub-system, identifying a candidate configuration that generates a load on a memory sub-system of a host system to decrease a characteristics of the memory sub-system of the host system, and updating a configuration of the host system based at least on the candidate configuration, wherein the updated configuration changes the memory sub-system of the host system to emulate the characteristic of the target memory sub-system.

Abstract: A request to retrieve data from a memory device of a memory sub-system can be received from a machine learning (ML) framework executing on a host system, where the data comprises a plurality of logical partitions. A set of parallel I/O threads can be initiated to retrieve the data from the memory device, where each I/O thread of the set of parallel I/O threads retrieves a different portion of the data from a different corresponding logical partition and stores the different portion of the data in a I/O buffer of a set of I/O buffers corresponding to the set of I/O threads in parallel. The different portion of the data can be successively provided from each I/O buffer to the ML framework, where the set of parallel I/O threads is to continually retrieve the data from the memory device until all of the data from the logical partitions has been provided to the ML framework.

Abstract: A key-value pair comprising a key and a value associated with the key is stored in a current segment of a data container. The key comprises a segment identifier identifying the current segment. The data container comprises a plurality of segments residing on a non-volatile memory device. Responsive to determining that a size of the current segment exceeds a threshold, a new segment is added to the container. The plurality of key-value pairs having respective current segment identifiers referencing one or more least recently created segments of the data container is deleted.

Abstract: A system includes a memory device a processing device, operatively coupled to the memory device. The processing device is configured to receive a request to identify a target key in a key-value store based on a specified key; identify, in at least one of a plurality of sequences of memory keys, the target key based on the specified key, where the plurality of sequences of memory keys includes a sequence of memory keys and a sequence of media keys that comprises designated media keys, where each of the designated media keys is designated as being deleted, where the identifying comprises comparing each of the designated media keys to the specified key; and perform a database operation using the target key.
