Hello, If you want to benefit from partition aware data loading, you must set up an affinity key field, without it SQL will make a full scan every time. If you don't plan to use SQL on Ignite's side, then you can set up a custom AffinityFunction <https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/cache/affinity/AffinityFunction.html> in your CacheConfiguration <https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/configuration/CacheConfiguration.html#setAffinity-org.apache.ignite.cache.affinity.AffinityFunction-> , which is not recommened due to potential complexity of this task.
