The effectiveness of this technique depends on whether the query can be run entirely in a streaming fashion. Some queries, such as SELECT * FROM table LIMIT 10 will scan only a few granules of the first few parts before reaching 10 results and returning the result to the user. This is also true for cases where the user orders the SELECT by a primary key field due to the optimize_read_in_order setting defaulting to 1. However, if the user runs SELECT a from table ORDER BY b LIMIT N, whereby the table is ordered by a and not by b, ClickHouse cannot avoid reading the entire table i.e., no early termination of the query is possible.
