Abstract
Techniques for issuing efficient writes to an erasure coded storage object in a distributed storage system via adaptive logging are provided. In one set of embodiments, a node of the system can receive a write request for updating one or more logical data blocks of the storage object and determine whether a size of the one or more logical data blocks meets or exceeds a threshold size. Upon determining that the size of the one or more logical data blocks meets or exceeds the threshold size, the node can allocate a segment in a capacity object of the storage object, write the one or more logical data blocks via a full stripe write to the segment, and write metadata for the one or more logical data blocks to a log record in a log of a metadata object of the storage object. The metadata written to the log record can include mappings between logical block addresses (LBAs) of the one or more logical data blocks and physical block addresses (PBAs) where the one or more logical data blocks reside in the segment.
