Error when using Percentile function

[mladen-djordjevic]

Specifications:

• Client Version: 6.3.0
• InfluxDB Version: 2.x
• JDK Version: 8
• Platform:

I am experiencing error when using the percentile function:
HTTP status code: 400; Message: error @5:5-5:15: undefined identifier percentile

After some investigation, it looks like in Flux the percentile function is renamed (changed) to quantile and Flux queries that are generated with influxdb-client-java using percentile function are no longer valid:

from(bucket:"events")
    |> range(start:2022-07-22T08:00:00.000000000Z, stop:2022-07-28T20:00:00.000000000Z)
    |> percentile(percentile:95.0)

Percentile function doc in influxdb-client-java:
https://github.com/influxdata/influxdb-client-java/tree/master/flux-dsl#percentile

Quantile function in Flux doc:
https://github.com/influxdata/flux/blob/master/docs/SPEC.md#quantile-selector

Please review my findings above. I am also happy to fix this with Pull Request.

Hi @mladen-djordjevic,

thanks for using our client and report this issue. We will take a look

As a workaround you can use https://github.com/influxdata/influxdb-client-java/tree/master/flux-dsl#custom-expressions

Thank you for the quick response. Custom expression is doing the job for now.

Best Regards.
