Research direction

Start by reading the existing btset -slice API and tracing the datoms path used by (first (datoms ...)). Determine the smallest API shape for retrieving one Datom without the full slice, then verify that the common entities and transacting uses avoid unnecessary work and preserve existing behavior.

Written by the indexing model from the issue text.

Description

As discussed on Slack.

Adding something like -slice-one to the btset which is more efficient than -slice would allow more efficient (first (datoms ...)) which is commonly used in entities and transacting.
