Hi, If you need write through, you should implement CacheStore interface [1]. But I'm not sure how you're going to work with files in this case. What if the entry that already exists is updated? [1] https://apacheignite.readme.io/docs/persistent-store -Val -- View this message in context:

Lieven, We plan to have a cluster of 16 nodes and the dynamic node groups using Ignite predicate. Each node will have the API Gateway, but only will be active at a time (floating IP). API Gateway will manage incoming HTTP requests. Each node is identical and will have same set of microservices.
