使用连接器将数据从 mongodb 导入 kafka 时，https://github.com/mongodb/mongo-kafka会抛出java.lang.IllegalStateException: Queue full.
我使用默认设置copy.existing.queue.size16000 和copy.existing: true. 我应该设置什么值？集合大小为10G。
环境：
mongo-kafka-connect: 1.0.0
Kafka: 2.4.0
Kafka-Connect: 2.4.0
MongoDB server: 3.6.14
mongodb-driver-sync: 3.12.1
