@WangXiangUSTC there're a few errors with binlog docker-compose. Could you help? drainer: ``` [2019/12/30 03:22:23.297 +00:00] [FATAL] [main.go:39] ["verifying flags failed, See 'drainer --help'."] [error="component drainer's config file /drainer.toml contained...

@july2993 There's still some problem with drainer and kafka. Drainer exits with 0 silently while kafka can't connect to zk.

@july2993 Thanks. I'll try this.

@july2993 I've done some basic testing, trying to setup ci for this scenario. You could make further test with https://github.com/moiot/gravity/tree/tidb-bidirection btw, default value for `stop-write-at-available-space` of pumper seems too big...

@july2993 any problem? If no, I'm planning to merge #253

贴下监控？配置没看出啥问题

I can't reproduce this. could you provide your config and log?

yes I do the same. A: create t wait until B has t B: drop t check t not exists on A

no. It's quite a few change. - use go-mysql's pos api to subscribe binlog - adapt mysql stream position to support both pos and gtid

从监控看问题是读源端慢。源端没有主键只有联合唯一键？ 这样（联合唯一键批量）读是会比较慢的，跟同步链路本身关系不大。可以尝试调低批量调高并发，具体还是要看下源端的情况。
