Offline Data Storage and Retrieval
Generally, SAW nodes in Cluster maintain the replica of data on each SAW node. If you are removing one SAW node, the data still be available in other nodes. But SAW cluster needs minimum 3 SAW nodes to work.
Thanks for responding on my query. In the current architechture, we have 3 hybrids and 3 SAW nodes. So in the proposed architechture, we will repurpose SAW 1 and SAW 2 with ESA 1 and ESA 2, SAW 3 with Archiver.
For this, we need to accomodate the SAW data. If it is stored offline how and where it can be done. Also how can we retrieve the same?
Thanks for more details. I believe, Avro files can be read using API built with different programming languages like java,python,..etc.,
So, you can move 1 Avro file to offline storage and try reading it with API. If that is readable, you can build analytics on that data.
Thanks for your generous response. It was of great help.
There is a query about warehouse. What is the expiry period of Data Warehouse(SAW nodes)?
