> When searching by those tags and a time interval, it will read everything from disk

That's what I'm asking, actually. Isn't Loki's proposition that it only indexes the tags and time interval? Do you mean that even filtering by that there's still a lot of data to go through?

Because it seems like you're saying it always fetches everything from disk.

If you specify a tag, like environment, it will not read the disk for data from other environments. But the tags like environment/host/timeframe are not enough if you want to query for something like error/exception/sessionid, and you might have to wait minutes/hours for a query which covers a lot of data.
