2020-10-13 04:17:57 UTC - Sijie Guo: You should use `num_messages_in_batch` in the metadata ---- 2020-10-13 06:52:19 UTC - dionjansen: @Sijie Guo so is the following correct? The metadata property `num_messages_in_batch` is optional so if `num_messages_in_batch` is set (whether to 1 or a number higher than 1) the payload should always be treated as a batch, otherwise it can be treated as a non-batched message. ----
