I am using region getall method to get values for all keys, but what i found is that for the key present in apache geode it gets data quickly but for one which is not present in apache geode. it calls the cache loader one by one. Is there any mechanism so that calling cacheloader can be made parallel.
calling getall in apache geode to getall data for the keys in the list is slow

I don't think there's a way of achieving this out of the box, at least not while using a single
Region.getAll()
operation. If I recall correctly, the servers just iterate through thekeys
and performs aget
on every single one, which ends up triggering theCacheLoader
execution.You could, however, achieve some degree of parallelism by splitting the set of
keys
into multiple sets, and launching different threads to execute theRegion.getAll()
operation using these smaller sets. The actual size of each set and the number of threads will depend on the ratio of cache hits / misses you expect, and your SLA requirements, of course.
