The (experimental) inverted index writes/reads files different from the
standard files written by the other skip indexes. The original problem
was that with database engine "ordinary", DROP TABLE of a table with
inverted index finds unknown files in persistence and complains. The
same will happen with engine "atomic" but deferred. As a hotfix, the
error was silenced by explicitly adding the four files created in a
specific test to the deletion code.
This PR tries a cleaner solution where all needed files are provided via
the normal checksum structure. One drawback remains which is that the
affected files were written earlier and we don't have their checksums
available. Therefore, the inverted index is currently excluded from
CHECK TABLE.
Minimal repro:
SET allow_experimental_inverted_index = 1;
DROP TABLE IF EXISTS tab;
CREATE TABLE tab(s String, INDEX af(s) TYPE inverted(2)) ENGINE = MergeTree() ORDER BY s;
INSERT INTO tab VALUES ('Alick a01');
CHECK TABLE tab;
DROP TABLE IF EXISTS tab;
run ./clickhouse-test with --db-engine Ordinary
