help on apisix http_logger

[Edda Dal Santo]

Hi.

We write to ask for some help on an issue we're facing with Apisix 
http-logger and which is blocking us in production. We set 
include_resp_body to true because we need to log response bodies to an 
external server which we use as a mirroring service. We have noticed 
that response bodies larger than 512 KB are being truncated and this is 
a problem for us because we need to handle bodies of several MBs in size 
without data loss. We didn't find any reference in the documentation 
about this limitation for the plugin and we wonder: where is this 512 KB 
threshold defined? Is it an internal setting of Apisix? Is it modifiable?
We assume that this is a common feature of all built-in logger plugins, 
so it wouldn't be any different using another one.

We’d really appreciate any hint/help on this, even negative responses 
are welcome. Could anybody tell us at least that what we want to obtain 
is not feasible?

Thanks,
Edda
