The way it handles different schemas and formats is very flexible. You can also do some customizations in the ETL process which is very helpful when you have multiple applications with different schemas. Not much, but I wish there was a way to map different databases using SQL queries. It would make it easier to do so. We are solving the problem of having heterogeneous data sources. We have different applications and each one has their own data format. We use Anzo to pull this data and store it into our data lake.
