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.
