Postgres to Postgres replication error in AWS DMS
I am getting below error while using AWS data migration service.
Source - One single postgres rds instance having multiple databases in it (80 GB)
Target - One single postgres rds instance where each src database will be a schema in same database
Number of tables - Total number of tables including all databases is around 200
Replication instance - t2.medium
I created four tasks for replicating four databases from source into four different schemas in target. But the fifth task for fifth database is failing with below error -
ERROR: all replication slots are in use;, Error while executing the query
How can I increase the replication slots so that dms can have 10 tasks running together?
Found the answer, There is an option to configure maximum number of replication slots in aws postgres rds instance which should solve my issue.
