Every id in a collection.
A drain can read the head repeatedly because moved rows leave the source.
A COPY leaves them, so it needs the full id set up front, and Milvus caps a
query at max-page rows and returns them in no particular order, so a single
page is not the collection.
The id space is therefore split into disjoint ranges, each fetched whole. A range that comes back full may have been truncated, so it is split at the median id of what came back. Nothing is assumed about ordering or about the shape of ids, and a range that cannot be split further raises rather than returning a short answer.

(all-ids coll)(all-ids coll base)Every id in coll matching the optional base filter expression, as a
vector. Raises rather than truncating.
Every id in `coll` matching the optional `base` filter expression, as a vector. Raises rather than truncating.
(rows-matching fetch filter-expr limit)Up to limit rows satisfying filter-expr, read through FETCH
((fn [filter-expr limit] rows)), which is never asked for more than
max-page. Within the cap this is one fetch; above it the matching rows are
gathered from disjoint id ranges, stopping once limit are held.
Raises rather than truncating.
Up to `limit` rows satisfying `filter-expr`, read through FETCH (`(fn [filter-expr limit] rows)`), which is never asked for more than `max-page`. Within the cap this is one fetch; above it the matching rows are gathered from disjoint id ranges, stopping once `limit` are held. Raises rather than truncating.
