what is the maximum http post body size for the TFX serving?

I can not find it anywhere in the https://www.tensorflow.org/tfx/serving/api_rest documentation nor in other parts of documentation. Most web servers have some default maximal value, which can be configured, but I have not found anything. I have features of varying sizes, some of them being over 1GB large, so I want to know what is the limit.

I read the source code, it seems that tfx is using http service implemented by libevent library.

Then I read the libevent code, the default body size is ((((ev_uint64_t)0xffffffffUL) << 32) | 0xffffffffUL) on 64-bit systems and ((ev_uint32_t)0xffffffffUL) on 32-bit systems. In other words, the largest unsigned integer. (You can search evhttp_set_max_body_size in libevent code.)
