Forwarding events from WinCC OA to OpenTSDB, which is based on HBase. Based on OpenTSDB Grafan can be used to build cool dashboards in a very fast way.
Live Example (my photovoltaic data) : http://220.127.116.11/grafana
On my test environment (i7 with 32gb RAM and 8 threads) i was able to push about 20000(!) values per second from my WinCC OA system to my Hadoop/HBase cluster. WinCC OA and the Hadoop Cluster are running on Hyper-V.
