Let us look at what happens when the time comes to scale the writes of the above workload. We have already discussed in a previous section that Aurora PostgreSQL can only scale to a maximum of 96 cores, or the write ceiling of the Aurora PostgreSQL database is capped at 120K transactions/second across all the transactions performed by the app and indexes on the various tables in the database. With YugabyteDB, a 63 node cluster would deliver 120K transactions/sec, a 106 node cluster would deliver over 200K transactions/sec.
