Set Python large payload sample threshold to 256 KiB#344
Merged
Conversation
Align the Durable Task SDK Python sample with the SDK default change (microsoft/durabletask-python#166): set threshold_bytes to 262,144 (256 KiB) in both worker and client, and raise the demo payload (input 10_000 -> 50_000, ~342 KB) so it still exceeds the threshold and externalizes.

Summary
Aligns the Durable Task SDK Python large-payload sample with the SDK default change (microsoft/durabletask-python#166), which lowers the default externalization threshold to 262,144 bytes (256 KiB) — matching the .NET SDK (microsoft/durabletask-dotnet#755) and the .NET samples (#343).
Changes (
samples/durable-task-sdks/python/large-payload/)worker.py+client.py—threshold_bytes1_024→262_144(256 KiB) in both (they must match), with updated comments.client.py— bumped the "large" demo input10_000→50_000(~342 KB) so it still exceeds the new threshold and externalizes. The small input (10) stays inline.README.md— updated the payload figure (70 KB → ~342 KB), the code snippet threshold, and the documented default (900 KB → 256 KiB).Verification
python -m py_compile worker.py client.py— clean."RECORD|" * 50_000= 350,000 bytes > 262,144, so the large payload externalizes; the small payload stays inline. (The byte-length check is pre-compression.)
