What is the impact of setting "max text repl size (B)" to -1?
What is the downside of setting "max text repl size (B)" to -1?


I would not set the value to -1 (limitless). I would instead find out the max datalength of your lob data and set it accordingly with a 10% buffer. This way you have more control of what and how much gets into distribution.

I can see that in an unlikely situation, setting of -1 can cause high network latency if the blob data to be replicated is of a much larger size.
