Jens Kleine-Herzbruch updated CAMEL-14281:
------------------------------------------
Description:
Currently, if two requests for the same cache key come in simultaneously, both
requests will execute the route decorated with the cache policy. If this route
includes expensive calculations/integrations this may be undesirable. Instead,
only the first request should kick off the real route, and the second should
block on the cache read until the result of the first route has entered the
cache.
Spring, for example, supports this with the "sync" parameter on @Cacheable.
