Apache ignite In-Memory Database

Question

I want to use ignite as a pure in memory db(all data/indexes is in memory) with persistence to disk (similar to Redis), when the service restarts all the data/indexes should be loaded into memory again (automatic warmup).

Update: There's actually two questions inline here:

1. Can I guarantee that the data is in memory including indexes? (AFAIK persistent-store doesn't guarantee it).
2. Can I warm the cache(including indexes) without writing Java? (implementing CacheStore as described here: https://apacheignite.readme.io/docs/data-loading#section-ignitecacheloadcache)

Answer 1

You can enable persistency through xml configuration: https://apacheignite.readme.io/v2.6/docs/distributed-persistent-store#section-usage
