+
+We’re thrilled to announce to the release of Apache Samza 1.2.0.
+
+Today Samza forms the backbone of hundreds of real-time production applications across a multitude of companies, such as LinkedIn, VMWare, Slack, Redfin among many others. Samza provides leading support for large-scale stateful stream processing with:
+
+* First class support for local state (with RocksDB store). This allows a stateful application to scale up to 1.1 Million events/sec on a single machine with SSD.
+
+* Support for incremental checkpointing of state instead of full snapshots. This enables Samza to scale to applications with very large state.
+
+* A fully asynchronous programming model that makes parallelizing remote calls efficient and effortless.
+
+* High level API for expressing complex stream processing pipelines in a few lines of code.
+
+* Beam Samza Runner that marries Beam’s best in class support for EventTime based windowed processing and sophisticated triggering with Samza’s stable and scalable stateful processing model.
+
+* A fully pluggable model for input sources (e.g. Kafka, Kinesis, DynamoDB streams etc.) and output systems (HDFS, Kafka, ElastiCache etc.).
+
+* A Table API that provides a common abstraction for accessing remote or local databases and allowing developers are able to "join" an input event stream with such a Table.
+
+* Flexible deployment model for running the applications in any hosting environment and with cluster managers other than YARN.
+
+* Features like canaries, upgrades and rollbacks that support extremely large deployments with minimal downtime.
+
+### **New Features, Upgrades and Bug Fixes:**
+This release brings the following features, upgrades, and capabilities:
+ * Upgrade to Kafka 2
+ * Beam integration with tables and integration with CouchBase
+ * Async high level api
+ * Bug fixes
+
+Full list of the jiras addressed in this release can be found [here](https://issues.apache.org/jira/issues/?jql=project%20%3D%20SAMZA%20AND%20fixVersion%20%3D%201.2).
