Thanks @mreso , LGTM.

many users ignore TS good examples. Micro batching is a good feature to boost TPS. We need promote it to a feature announcement, not just an example.

can we move extract the core parts such as micro_batching.py and micro_batch_handler.py to handler utils so that users can easily plugged in customer handler?

lxning · 2023-04-04T18:07:22Z

examples/micro_batching/micro_batching_handler.py

+    def initialize(self, ctx):
+        super().initialize(ctx)
+
+        config_file = Path(ctx.system_properties["model_dir"], "micro_batching.json")


can we use the new feature model-config.yaml to set these parameters?

all of the parameters can be accessed via ctx. model_yaml_config

lxning · 2023-04-04T18:10:30Z

examples/micro_batching/micro_batching_handler.py

+                self.handle.parallelism = config["parallelism"]
+                self.handle.micro_batch_size = config["micro_batch_size"]


users may be thought "parallelism" and "micro_batch_size" are related to large model parallel. Can we have a good naming to differentiate?

Sure, can just call them mb_size and mb_parallelism

Went with ["micro_batching"]["parallelism"], that should be sufficient for users to differentiate.

ts/handler_utils is handler utils dir. could you move utils/micro_batching.py to ts/handler_utils/microbatching?

lxning · 2023-05-24T19:19:09Z

ts/handler_utils/__init__.py

+from .micro_batching import MicroBatching
+
+__all__ = ["MicroBatching"]


this needs to be removed.

@mreso I see the MacOS CI is failing because of Resource issue. Can you please check if its because of this PR?
