skywalking export trace data to kafka,missing a lot of trace data

[ahseezre]

I configured skywalking to export data to kafka. By comparing the data of consuming kafka with the data on skywalking-ui, kafka received very little data, only about 20% of that on skywalking-ui. After investigation, the logs of skywalking-oap and kafka were normal, with no message backlog, and the sampling rate was 100%.
