As metric names and labels are highly repetitive it is recommended that the serialized metrics are compressed prior to sending them to the broker if the serialized uncompressed size exceeds 1000 bytes.

The broker will return a prioritized list of supported compression types in the GetTelemetrySubscriptionsResponse.AcceptedCompressionTypes array, the client is free to pick any supported compression type but should pick the first mutually supported type in the returned list. If the AcceptedCompressionTypes array is empty the client must send metrics uncompressed. The default compression types list as returned from the broker should be: ZStd, LZ4, GZip, Snappy.

The PushTelemtryRequest.CompressionType must then be set to the corresponding compression type value as defined for MessageV2.
