Abstract
Techniques for efficiently flushing a user data log may postpone or delay establishing chains of metadata pages used as mapping information to map logical addresses to storage locations of content stored at the logical addresses. Processing can include: receiving a write operation that writes data to a logical address; storing an entry for the write operation in the user data log; and flushing the entry from the user data log. Flushing can include storing a metadata log entry in a metadata log, wherein the metadata log entry represents a binding of the logical address to a data block including the data stored at the logical address; and destaging the metadata log entry. Destaging can include updating mapping information used to map the logical address to the data block. The mapping information can include a metadata page in accordance with the metadata log entry.
