Abstract: Disclosed are techniques for managing context information for data stored within a computing device. According to some embodiments, the method can include the steps of (1) loading, into a volatile memory of the computing device, the context information from a non-volatile memory of the computing device, where the context information is separated into a plurality of portions, and each portion of the plurality of portions is separated into a plurality of sub-portions, (2) writing transactions into a log stored within the non-volatile memory, and (3) each time a condition is satisfied: identifying a next sub-portion to be processed, where the next sub-portion is included in the plurality of sub-portions of a current portion being processed, identifying a portion of the context information that corresponds to the next sub-portion, converting the portion from a first format to a second format, and writing the portion into the non-volatile memory.

Abstract: Disclosed herein are techniques for balancing write commands directed to a non-volatile memory. According to some embodiments, a method may include caching a plurality of write commands into a write cache, and, in response to determining that an available capacity of the write cache satisfies a first threshold value: performing at least one write operation by directing data associated with the write commands in the write cache to the first partition of the non-volatile memory in response to determining that an available capacity of a first partition of the non-volatile memory satisfies a second threshold value; and performing at least one write operation by directing data associated with the write commands in the write cache to a second partition of the non-volatile memory in response to determining that the available capacity of the first partition of the non-volatile memory does not satisfy the second threshold value.
