Delta Lake

Delta Lake's primary language is Scala, which can be challenging for developers primarily working with other languages like Python or Java.

While Delta Lake supports Scala and Python natively, support for other languages is limited and often relies on community-maintained libraries which may not be as robust or up-to-date.

Enabling ACID transactions can introduce performance overhead, especially in large-scale environments where every transaction needs to be validated and committed atomically.

Setting up Delta Lake requires configuring Spark clusters, managing storage layers, and ensuring compatibility with other big data tools, which can be complex and time-consuming.
