Data Lake Integration Design Principles
I was talking with a friend at Gartner and he said that (as per the current stats), most of the data lake implementations are failures. I asked what most meant and he replied, “Over 95 percent.” I was surprised and didn’t believe him. I also joked that probably Gartner should publish a paper on causes of failures for data lake implementations, classify them, and provide percentages for each of the causes. More seriously, a lot of data lake implementations do fail or are abandoned for various reasons. In the Chicago area, I know of at least two huge corporations that abandoned such an effort and went back to their proprietary data warehouse platforms.
