23 Nov 2020 We’ve taken Azure Synapse for a spin

Microsoft has recently taken us on a word lingo with the launch of Azure Synapse Analytics. At Kohera, we've experienced some confusion in the market between Azure Synapse as a standalone product and Azure Synapse Analytics as a SaaS platform. We guess it's time to set things straight once and for all, or at least for a while.

03 Aug 2020 Caching in Databricks?
Yes, you can!

16 Dec 2018 All I want for Christmas is you

Oh, this is cheesy, can’t believe we could ever dare to mention Mariah Carey in our blogpost series.  Well, the holiday season is starting, so there is no escape at all 😊. By the way, what I meant with the title was: All I need for Christmas is you… Azure Data Flow.
