Hi, Are you using Spring-boot 1.5.11+? Try to explicitly set H2 version to 1.4.196 if you have it in your pom.xml, this seems to be a known issue https://issues.apache.org/jira/browse/IGNITE-8197 related to later H2 versions.
Also note that you have 2018-05-11 16:00:23.114 WARN 15888 --- [ main] org.apache.ignite.internal.IgniteKernal : Nodes started on local machine require more than 20% of physical RAM what can lead to significant slowdown due to swapping (please decrease JVM heap size, data region size or checkpoint buffer size) [required=3652MB, available=1830MB] In your logs, consider to apply this suggestion if you will experience performance drops.
