apply_filters( 'split_the_query', bool $split_the_query, WP_Query $query, string $old_request, string[] $clauses )

Since
3.4.0, 6.6.0
Filters whether to split the query.

Description

Splitting the query will cause it to fetch just the IDs of the found posts (and then individually fetch each post by ID), rather than fetching every complete row at once. One massive result vs. many small results.
