  1. kafka server down了
    重新启动后,

connector必须要重新启动,然后offset丢失了
通过设置0ffset来解决
kafka.tools.ConsoleConsumer --bootstrap-server xx:9092 --topic ds.ds.topic --partition 0 --consumer.config config/consumer.properties --offset 4020000

2. confluent 3.2.1, reactor 0.2.5写elastic search 会丢失数据
升级到3.2.2,reactor0.2.6解决

3.es中已有数据有很多时,1亿以上时,upsert很慢
