Wow. For me personally, that sounds like Distributed Event Sourcing Storage at scale.

I don't know if anybody observed but the article is so damn intuitive, it literally covered almost all the things. Often times when such articles are published I have to google it deeper to get a sense of its practical use.

I have one query: How efficient is the deletion (from disk) of chunks in a new distributed model?

View on HN

It basically boils down to deleting a bunch of files on disk. The fact that it is distributed doesn't affect efficiency too much; it is basically a delete sent to all nodes, followed by a two-phase commit.

The upside of deleting entire tables (chunks) like this is that you don't pay the same PostgreSQL vacuuming cost normally associated with row-by-row deletes.

Thanks.
