A company uses an Amazon Aurora PostgreSQL global database that has two secondary AWS Regions.

Step 1: Reducing Replication Lag in Aurora Global DatabasesIn Amazon Aurora global databases, write operations on the primary cluster can be delayed due to the time it takes to replicate to secondary clusters, especially when there are multiple secondary regions involved.

Issue: The write operations are occasionally blocked due to the RPO setting, which guarantees replication within 60 seconds.

Action: Remove one of the secondary clusters from the global database.

Why: Fewer secondary clusters will reduce the overall replication lag, improving write performance and reducing the frequency of blocked writes.
