Hi, When running your code I created the cache as follows: IgniteCache<BinaryObject, BinaryObject> employeeCache = ignite.getOrCreateCache("employeeCache").withKeepBinary();
With the ".WithKeepBinary()" flag set code works, otherwise there are serialization errors. If you still get errors w/this flag set, send a reproducer, and I'll take a look. more info: https://www.gridgain.com/docs/latest/developers-guide/key-value-api/binary-objects Binary Objects Example: https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/binary/datagrid/CacheClientBinaryPutGetExample.java Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
