Abstract
A technique for storing data in a log receives a set of sequential requests, each request specifying data to be written to a data object served by a data storage system. The data specified by respective ones of the requests is placed into respective lockable units of storage for the log, such that the data of no two sequential requests are stored within the same lockable unit. Each lockable unit is locked for access by a writer when being written, and unlocked when not being written, and is configured to store data specified by multiple requests. Completion of each of the requests is acknowledged in response to placing the data specified by the respective request in one of the lockable units of storage. The log may also be partitioned, with individual partitions being used to store data specified by requests having specific request sizes.
