This operation is not transactional. It calls broadcast closure that deletes all primary keys from remote nodes.
This is potentially an expensive operation as listeners are invoked.
Use clear() to avoid this.

Cache returned by this method will not be forced to deserialize binary objects, so keys and values will be returned from cache API methods without changes. Therefore, signature of the cache can contain only following types:
org.apache.ignite.binary.BinaryObject for binary classesString and array of StringsUUID and array of UUIDsDate and array of DatesTimestamp and array of Timestamps
For example, if you use Integer as a key and Value class as a value
(which will be stored in binary format), you should acquire following projection
to avoid deserialization:
