How to slow down the flow of archivelogs between principal and standby?

in High Availability Data Guard, Sharding and Global Data Services (MOSC) 8 commentsAnswered

I am running database enterprise edition 19CR25 on RH7

I have a dataguard environment the principal database is in city A and the standby in city B - there is a 100mb tunnel connecting them and many other things - its capacity is about 90% full.
What I have been tasked to do:
1- Update a 1.4T table - the two blobs columns are the ones being updated; 135,000 rows
2- This update generates a total of 400G of archive logs - each archivelog is around 50M
3- I have tested the scripts updating 20k rows at a time- we generate between 70G and 80G of archive logs -These tests has been carried out in a test environment with no standby db attached to it.

Howdy, Stranger!
