ApproximateChunkRate

Approximate a particular rate of chunks per second in the output.

This node can be used to reduce the effective update rate of a streaming pipeline, for example to 5 Hz. As a result, the node will only output new data 5 times a second. However, since the input to this node comes in at a certain update rate, if the two rates are not divisors of each other, the output will not be exactly 5 Hz (e.g., every 3 cycles, the data may be empty). To get a more regular chunk rate, the node Regulate Chunk Sizes can be used after this node. Version 1.0.0
