Caching the Result of Queries that Fail¶

By default, the result of queries that fail is not cached, but you can cache it if you want.

For example, let us say that you execute a union view and one of the branches of the union fails but you still want to cache the result obtained from the other branches of the union. To do this, add the cache_load_on_error parameter to the CONTEXT clause with the value true.

For example:

SELECT *
FROM incidents
CONTEXT (
      'cache_preload' = 'true'
    , 'cache_invalidate' = 'all_rows'
    , 'cache_load_on_error' = 'true'
    , 'cache_wait_for_load' = 'true'
    , 'cache_return_query_results' = 'false')
