Thread: Logical replication and xids

Logical replication and xids

From

How is the initial snapshot executed in Postgres 10 logical replication? Mainly, I’m wondering if it would hold open a
transactionid on the publishing database the entire time.  

(I’m dealing with several databases that are quite large with tables I want to replicate that are up to 4 or 5 TB, and
I’mworried about running out of xids while the initial snapshot is sent.) 

Thank you,
Natalie
