On sled 0.31 the memory growth does not run away as with the earlier version. Note that some in-memory metadata tracking does accrue as nodes split and sled tracks where to find them in the future when the actual data is paged in. But this is still a fraction of data stored. The important thing is that sled is not stable yet. Don't bet your business on databases less than 5 years old. Sled doesn't turn 5 for a few more months, and I'm ironing out a few issues still that relate to production readiness. For now, treat it as a cache, as a responsible SRE would treat any database younger than 5 years old.
