Dear postgresql community,

I have a question regarding understanding the implementation logic 
behind logical replication.

Assume a replication slot created on the master node, will more and more 
data get piled up in the slot and the size of replication slot 
continuously increase if there is no slave reading/dequeuing data out of 
this slot or very slowly, thus incurring high I/Os and slow down the 
transaction throughput?

Looking forward to your explanation.


Kindly review and please share your comments on this matter.
