Frozen Indices
Frozen Indices
By default, Elasticsearch SQL doesn’t search frozen indices. To search frozen indices, use one of the following features:
dedicated configuration parameter
Set to true
properties index_include_frozen
in the SQL search API or index.include.frozen
in the drivers to include frozen indices.
dedicated keyword
Explicitly perform the inclusion through the dedicated FROZEN
keyword in the FROM
clause or INCLUDE FROZEN
in the SHOW
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

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.
