BaseExporter<Metric>

I created a basic exporter to write to MS SQL database. So export method looks in this way:

        public override ExportResult Export(in Batch<Metric> batch)
        {
            try
            {
                ExportToDatabase(batch);
                return ExportResult.Success;
            }
            catch (Exception ex)
            {
                _logger?.LogError("Failed to export metrics to SQL database: {0}", ex.Message);
                return ExportResult.Failure;
            }
        }

At run time no errors are occurs, ExportResult.Success is returned. No new data was generated, but Export was called again and again with exact same batch. Is this expected behavior ? What do I miss ?

It'd be a bug if exact same data is repeatedly sent!
Are you using Cumulative temporality or Delta? In cumulative, even when no updates, the data from the start of the process is always sent (but it'll have different end_timestamps).
