When is tail sampling supported? #10765

Hi, Due to the sampling rate, request may not be collected when the request is abnormal. So tail sampling capability is needed to collect all the problems when they occur. When is tail sampling supported?

We are considering the following implementation, but it is undecided when it will be implemented.

Although the fundamental goal is different, I think it can achieve the same effect as tail sampling.

Efficiency of hbase storage space

  1. Storing span data with high sampling rate in hbase
  2. After a certain period of time, the trace is deleted through a rule-based filter.
