How is the initial snapshot executed in Postgres 10 logical replication? Mainly, I’m wondering if it would hold open a transaction id 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’m worried about running out of xids while the initial snapshot is sent.)
Thank you,
Natalie
