Hi All, As a simple native persistence node, if kill and reboot sometime NPE may thrown.
From the code the really root cause should be the BPlusTree#doPut #putDown's Result is not Expected, But even in the CacheObjectBinaryProcessorImpl#metadata the holder != null should be checked earlier Regards Aaron org.apache.ignite.IgniteCheckedException: null at org.apache.ignite.internal.util.IgniteUtils.cast(IgniteUtils.java:7252) ~[ignite-core-2.3.0.jar!/:2.3.0] at
