    [FAB-13656] Size-based snapshotting · 566562e7
    Jay Guo authored
    Instead of taking snapshot every N blocks, this CR
    changes it to taking snapshot every N bytes.
    This also sets default SnapshotInterval to 100MB, if
    it's unset. Otherwise data in memory is never compacted
    till OOM.
    Meanwhile, DefaultSnapshotCatchUpEntries is shrunk so
    it does not take too much space to preserve extra entries
    every time a snapshot is taken. Slow nodes are catching up
    using blockpuller, which is also efficient.
