mastodon 4.7.3
The OpenSearch Data Prepper maintainers are happy to announce the release of Data Prepper 2.15. This version adds the ability to ingest data from Apache Iceberg, making it easier to keep OpenSearch in sync without custom pipelines. It also extends Prometheus support with a remote-write source and the ability to send data to open source Prometheus.
Big kudos to the community for keeping this project moving forward. Read the full blog here: https://bit.ly/4sotUhD
