Unable to Delete Points for Specific Tag Using Delete API in InfluxDB

InfluxDB 2
1

Hi InfluxDB Community,

I’m currently trying to delete all data points associated with a specific tag (BatchId) in my InfluxDB bucket, but I’m unable to achieve it. Here’s what I’ve done so far:

  1. I’m using the DeleteApi from the .NET InfluxDB client library.
  2. I’ve set up a predicate to match all data for BatchId:

csharp
using var client = InfluxDBClientFactory.Create(influxUrl, token);

var deleteApi = client.GetDeleteApi();

var startTime = DateTime.MinValue.ToUniversalTime();
var stopTime = DateTime.MaxValue.ToUniversalTime();

var predicate = "“Tag=“BatchId””;
deleteApi.Delete(startTime, stopTime, predicate, bucket1, org);

Despite this, no data points are being deleted. I don’t receive any specific error messages, and the operation appears to complete without issues.
