 From version 0.5.3 onwards, zio-grpc provides backpressure support for server
 streaming RPCs. In case the call is not capable to sending additional messages
-without buffering (as determined by [`ServerCall.isReady`](https://grpc.github.io/grpc-java/javadoc/io/grpc/ServerCall.html#isReady])), sending messages from the queue associated with server response `Stream` will stop. The default size of this queue is `16`,  and can be configured by setting the system property `zio_grpc.backpressure_queue_size` or the environment variable `ZIO_GRPC_BACKPRESSURE_QUEUE_SIZE`.

The default size of this queue is `16`,  and can be configured by setting the system property `zio_grpc.backpressure_queue_size` or the environment variable `ZIO_GRPC_BACKPRESSURE_QUEUE_SIZE`. Setting the value to `0` or a negative number will disable buffering but keep the back pressure at the chunk level (`isReady` will be checked after processing each chunk instead of each message).
