我们在 GKE 集群上部署了 debezium mysql connectors。但是 pod 失败，原因是： java.lang.OutOfMemoryError: Java heap space 。将 jvm 选项增加到 10g，但仍然因同样的问题而失败。
以下是我的配置属性：
singleTopicMode=true
databaseManagementSystem=mysql
debezium.offset.flush.timeout.ms=60000
debezium.offset.flush.interval.ms=10000
debezium.max.request.size=1048
debezium.max.queue.size=65536
debezium.max.batch.size=16384
debezium.HEAP_OPTS='-Xms10g -Xmx10g'
