Georg Henzler commented on SLING-6126:
--------------------------------------

[~drfits] Would using hc.async.cronExpression (see 
https://sling.apache.org/documentation/bundles/sling-health-check-tool.html#configuring-health-checks)
 be an option? The problem of just extending the TTL is, that users calling the 
long-running HC after a TTL has expired will not receive a result but a timeout 
(only a reload after 3-5 minutes gives an adequate result then). Using an async 
HC will never return a timeout (but always the last result).

> Currently there is no ability to specify TTL for separate health check.
> Ex.: in my case "hc" validating against repository about 3-5 minutes 
> therefore I couldn't specify TTL globally to not impact on other "hc" 
> results. This "hc" I couldn't execute by scheduler to prevent CPU from high 
> loading, also results for this check remains relevant for an 1-3 hours.
> Therefore if it make sense not only for me I've added "[pull 
> request|https://github.com/apache/sling/pull/180]"; for this functionality:
> * If property "hc.ttl" specified within HC - it will be used as TTL for 
> result, otherwise cache will use default TTL value
