FYI: 1 - About error: "snapshot more than 300MB", I think all columns of the table are loaded in RAM, independently these are used or no , is this possible ?
2 Apache Flink 1.2 is "ready" to docker, they had some changes to be more compatible Flink 6369 <https://issues.apache.org/jira/browse/FLINK-6369>, Flink 6572 <https://issues.apache.org/jira/browse/FLINK-6572>, Flink 4308 <https://issues.apache.org/jira/browse/FLINK-4308>,Flink 4326 <https://issues.apache.org/jira/browse/FLINK-4326> (This can be "an inspiration" for Kylin )
