Some new stuff in here I didn't know fully, but otherwise guess I had a good enough sense about it. Never understood what a websocket is, so maybe I'll make a point to read something about that (now that I know how they fit in).
Would be curious to learn more about indexing, another time, as that sounds interesting but complex (and I'll likely never need to concern myself with details in practice since I don't dev)
WebSockets are simply a bidirectional communication protocol
Both parties can talk at once instead of client asks, server responds
Indexing is like making a directory of all noted that have certain criteria.
I see. It at all what I had imagined.
And yes, I have a vague sense of what indexing does, from having joined some large dbs here and there along the way, and learning it worked faster if I enabled some index option. But I'm sure the details are interesting, and that there's lots of room for different choices that fall under the heading of "indexing".
Not* at all (regarding web socket)
