This does not look correct. All items after 50000 seem to be sent separately. If your case is that you have a lot of log messages with small |

Not all items after 50000 seem to be sent separately, it's every 50000 items to be sent separately, In this case, limiting the number of messages is more accurate than limiting the size of the log, and it may be better to limit the number of messages and the size of the log at the same time. |

Still, where is that 50000 coming from? Take the size of |
|
Similar to 1M of log data size, 50000 is an experience value which can make size of message under the safe line. And agree with you, logically vertexLog.Size() is much better but it's so expensive. Considering that this kind of scene is relatively rare, other two methods is enough, which one you prefer? |
I mean that there is no actual known limit now. Sometimes the limit might be 1M (eg. if it is a single log) but if there are a lot of items it could be much higher (1M + 50K*empty record size). We should stick to one precise limit. |
|
I think the server's sending buffer limit should be consistent with the client's receiving buffer limit (now it's 16M) |
|
There is no need to set it very big as it also means that the client view becomes less responsive. I think 1MB is fine, just need to count it correctly. |

you can make this global and move setting it to init()

after first big message the retry always be true and there is an endless loop.

hmm, looks weird indeed. maybe the retry := false should be inside the for

fix issue in #1539
when run maven compile in Dockerfile there are a lot of log vertex in status grpc response(>200000) . The grpc header and other fields in vertex message create grpc message exceeded 20M, which cause receiving buffer in buildctl overflow
