QUESTION
So I'm trying to build a Discord bot. These types of threads tend to get downvoted a lot on stackoverflow, so I'm hoping this doesn't happen to me.
This particular feature is acting as a temporary solution to my dashboard problem. Due to the nature of glitch.com's hosting, it's supposed to fall asleep after 5 minutes of http inactivity. I solved that already by adding a script that pings the URL every 4 minutes, but that caused another issue. I think what's happening is that because that script and the bot script are constantly running, and never technically 'finish', it never lets any incoming connection actually load the webpage. So my solution to that problem was to create another glitch project that would act as the dashboard website, and transfer information from the bot project. Of course then I'd need to create more scripts that communicate with each other via some internet protocol. The info recorded by the bot is all recorded in a private JSON database using the node-json-db npm library.
My problem is: I don't know what protocol would be best for this kind of thing. Even if I did know, then I'd have to go digging through the docs for the info I'm looking for.
My question is: What protocol should I use, and what docs do I need to read for this?
I've included some snippets of the code here:
The bot's server code (where I would add the script for communicating with the dashboard):

QUESTION
We are getting conflicting reports on the maximum size of JSON blobs that DB2 will allow queries on (e.g. functions like JSON_VAL and JSON_TABLE.)
There is evidence that it is limited to 16M, but I have found nothing conclusive. For example, here is a link to an IBM tech note regarding DB2 11 for z/OS. The Setup & Configuration section shows DB2’s definitions for SYSTOOLS.BSON2JSON
, which seems to declare the BSON value as a 16M CLOB.
On the other hand, one source told me that larger sizes ARE allowed but it will not perform well due to DB2's inability to cache a value larger than 16M. If true, this would at least allow us to run BSON queries in our development environment, or for one-time data extraction.
Can anyone point to a more definitive answer?

Answered 2017-Jun-29 at 14:07IBM confirmed in response to a support request that there is a 16 MB limit, imposed by the JSON2BSON
and BSON2JSON
functions. They note that MongoDB has the same limit.
They implied that if you implemented your own versions of JSON2BSON
and BSON2JSON
in C or Java, you could get around the limit. But they have no plans to increase the limit themselves, presumably because the values would not be cacheable by DB2.
