About SlateDB
Introduction SlateDB is an embedded storage engine built as a log structured merge tree. Unlike traditional LSM tree storage engines, SlateDB writes data to object storage (S3, GCS, ABS, MinIO, Tigris, and so on).

The trade off is that object storage has a higher latency and higher API cost than local disk. To mitigate high write API costs (PUTs), SlateDB batches writes. Rather than writing every put() call to object storage, MemTables are flushed periodically to object storage as a string…
