Binary logging is great, and certainly do-able. Here is what I think the negatives are: The method by which binary logs can achieve reduced sizes, especially when the bulk of the data is ascii-based context, is using schemas. For example, log the function name as an enum and extrapolate back to the readable form in post-processing. This is especially cumbersome for code bases with ad-hoc logging and lots of churn, as the schema must continually be maintained. -Noah -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
