S2

Object storage has been nothing short of revolutionary. S3 broke ground in 2006 with simple storage operations on named objects – and 18 years later, S3 Express One Zone even allows appends. But ultimately, object storage is all about blobs and byte ranges. It is best for data at rest. Our vision of stream storage is predicated on the idea that the demands of data in motion need a fresh perspective.

With S2, you are elevated to the natural granularity of records. Writes to an S2 stream are appended at the tail, and even if multiple writers are acting at a time, S2 will durably sequence all records. S2 takes care of serving your reads efficiently, whether you need to start streaming from seconds ago or years. Streams can also be tailed in real-time, which is not possible with a blob in S3.
