Functions

cleanup_datastore_key_range_query

Checks and cleans up a datastore key range query Returns: (prefix, start_bound, end_bound, count) or error The returned count is the effective item count limit: it falls back to the configured maximum when the caller did not provide one, so that callers can forward it to the datastore scan instead of running an unbounded enumeration. Note: only useful to cleanup user-supplied requests (API/ABI)

For lexicographically ordered keys, gets the upper and lower bound of keys matching a prefix.

range_intersection

Return the intersection of two ranges
