Hi I'm trying to use ignite to perform some computations over a large size of data (3M objects) and quickly hit the GC overhead limit memory.
In order to test i'm using a single machine with one node and 10g of memory. The example developed is computing the sum of a particular attribute of these objects. the sum is achieved by iterating over all cache objects. I tried different configurations , following the user doc found on ignite website, even with off-heap or swap, i have a memory leak. It seems that ignite uses arraylist to collect itterated data. (no pagination is done to collect data). ?? I wanted to know the limitation (approximative memory size / numbre of elements that can be achieved with such a configuration) and the best pratices to customise cache and fastest acces to these caches. I' would be also interested in performance stats if available and recomended configurations.
