Ravi, IgniteCache does not have a method like getAll() because this can simply trigger an OOME on the node that receiving the data.
If you want to process all entries on a single node, you can use IgniteCache#query() method and pass an instance of ScanQuery object to this method. Resulting cursor will allow you to iterate over cache entries. You can refer to [1] for more details. Note that, generally, such an approach is not very efficient because you are sending a lot of data across the network. You may want to exploit Ignite compute functionality and collocate your computations with data. In this case only small objects responsible for the computations and computation results will be sent across the network. The approach is described in [2] Hope this helps, AG ------ [1] https://apacheignite.readme.io/docs/cache-queries [2] https://apacheignite.readme.io/docs/collocate-compute-and-data
