Currently, metric data is sent periodically, but I need to send it whenever I want.

My scenario is different. Some metric data needs to be sent every minute, another set every 30 minutes, and some counters should be sent only when they are updated. So, periodic sending is not feasible. If I set it to 1 minute, it sends all metric data with previous values, unnecessarily filling the server storage with duplicate data.

You can implement your own MetricReader that suits your requirements.

You might like delta temporality metrics.. Rather than recording the cumulative state of all measurements, they record the changes since the last report. If a particular series has no new measurements, it won't be exported.
