This is a low-level embedded db that would be used by sql databases/query engines/streaming engines/etc rather than something that's likely to make sense for you to use as an application developer. It sits in a similar space to RocksDB and LevelDB. You generally can't use object storage directly for this stuff; if you have a high volume of writes, it's incredibly slow (and expensive) to write them individually to s3. Similarly, on the read side you want to be able to cache data on local disk & memory to reduce query latency and cost.
