in the drivers to include frozen indices. - dedicated keyword
-
Explicitly perform the inclusion through the dedicated
FROZEN
keyword in theFROM
clause orINCLUDE FROZEN
in theSHOW
commands:
SHOW TABLES INCLUDE FROZEN; catalog | name | type | kind ---------------+---------------+----------+--------------- javaRestTest |archive |TABLE |FROZEN INDEX javaRestTest |emp |TABLE |INDEX javaRestTest |employees |VIEW |ALIAS javaRestTest |library |TABLE |INDEX
SELECT * FROM FROZEN archive LIMIT 1; author | name | page_count | release_date -----------------+--------------------+---------------+-------------------- James S.A. Corey |Leviathan Wakes |561 |2011-06-02T00:00:00Z
Unless enabled, frozen indices are completely ignored; it is as if they do not exist and as such, queries ran against them are likely to fail.
