Is there a RDS aurora synchronous read replica?

If I understand correctly, Amazon Aurora has asynchronous read replica. So, we can get some read lag (it seems, lag is about 100 ms).

I need synchronous read replica. So, can I set such type of replicate for Amazon Aurora for PostgreSQL?

If you need a synchronous read replica I would recommend using a write-through cache architecture using ElastiCache "in front" of Aurora or similar to help scale out reads.

Sorry but you can't change Aurora Replication type, Aurora is Amazon Aurora has asynchronous read replica but the lag isn't a major problem normally it is just a few milliseconds, not all the time 100 ms.

For additional information please refer to https://aws.amazon.com/rds/aurora/faqs/
