> Open container replicas will not have a container merkle tree so that we do
> not need to keep updating this with every write request. Instead, the tree
> will be created on container close from the chunk checksums that are stored
> in RocksDB. Since these checksums should have been verified somewhat recently
> (with write checksum verification enabled), container close will build the
> merkle tree from these values without reading actual data blocks. Since
> should just be a hash of values stored contiguously in RocksDB, it should be
> a fast operation. The container scanner will come back asynchronously to
> update update the checksums based on the data it sees on disk at that time.
