Setting max message len seems to have no affect

Hi, could you show us how did you set the size limit? TiKV also use these settings and they works just fine.

I do exactly what you do. I’ll try to make a minimal repro.

But have you verified you can create a 5Mb message with your settings ? You set them to 10MB but perhaps your messages are never over the 4MB limit in which case you wouldn’t see it

I’ve just verified that I can decrease the amount, say to 1024, and it reports this value on the grpc error, but I cannot increase it past 4MB

[m4b]

Actually sorry, I cannot decrease max read either; only max send. I believe max send value is correctly modified, since I’m definitely sending large messages over 4MB but the max receive won’t take them.

It seems max send is recognized but max read seems to be completely ignored.

We have test cases covering it. :)

Please also make sure you modify the size limit on the server side too, just as we do.

Arghhhhhhhhh didn’t even occur to me that would be required on server too, but of course.

Thanks for the pointer! Works as expected, closing this :)
