OpenSearch sink not rolling over the index after upgrading from 2.7 to 2.10

Since migrating from 2.7.0 to 2.10.1 the index id stayed at the same number (000056) and is no longer rolling over. You can see below that previously indexes would be rolled around 500mb but this latest one is now at 108.5gb. Number of documents used to be around 300000 but now it's more than 73 million. Did I miss some configuration?

Start by reproducing the supplied Data Prepper configuration with the OpenSearch sink and compare index rollover behavior between versions 2.7.0 and 2.10.1. Trace the trace-analytics-raw index rollover path and verify that indexes again roll over near the previously observed 500 MB size and document count.
