caching - Sql query over Ignite CacheStore or over database -


i beginner ignite, have puzzles, 1 of follows:when try query cache, whether can if memory contains or not. if not, whether query database? if not,how achieve such way? please me if know.thx.

queries work on in-memory data only. can either use key access (operations get(), getall(), etc.) , utilize automatic read-through persistence store, or manually preload data before running queries. information on how load large data set cache, see page: https://apacheignite.readme.io/docs/data-loading
