>
> In some workloads, particularly those which get good compression rates of the
> underlying data (eg via dictionary coding), the WAL becomes a big bottleneck
> for write performance. In addition, the large size of WALs can often mean
> that old WALs get GCed rapidly and cause lagging replicas to get evicted
> after only a temporary bout of slowness. Making WALs smaller would mean that
> we can retain more history without the cost of disk space.
