What is the difference between delta lake (Databricks) and Delta Lake (Open Source -Maven) ?

[Taha]

Delta lake on Databricks and OS Delta are identical in terms of API compatibility and functionality. The main differences are feature of life improvements. An example for AWS is an S3 commit service that Databricks manages which helps with eventual consistency limitations on S3.
