Description
Today, writing new deltas entails rewriting entire tablet metadata files in order to track the newly-created block ids. Even if the delta were on the order of kilobytes, the tablet metadata files could be on the order of megabytes, so the relative cost for this small amount of data is quite high, considering the amount of the metadata.
This could be improved by batching such delta flushes, or by revamping tablet metadata entirely to batch any operations that require metadata updates.
