+### Patch async-compression to compress responses in streaming ([PR #1604](https://github.com/apollographql/router/issues/1604))
+
+async-compression is a dependency used for response compression. Its implementation accumulates the entire compressed response
+in memory before sending it, which creates problems for deferred responses, where we want the responses to come as soon as
+possible, and not all at once after a while.
