Rick Whiting
Working with ever-growing volumes of data continues to be a challenge for business and organizations. Here are 10 cool big data tools that caught our attention in 2021.

Databricks Delta Sharing
Databricks launched the Delta Sharing initiative in June to create an open-source data sharing protocol for securely sharing data across organizations in real time, independent of the platform on which the data resides.
Delta Sharing, included within the open-source Delta Lake 1.0 project, establishes a common standard for sharing all data types—structured and unstructured—with an open protocol that can be used in SQL, visual analytics tools and programming languages such as Python and R. Large-scale datasets also can be shared in the Apache Parquet and Delta Lake formats in real time without copying.
Delta Sharing is the latest open-source initiative from Databricks, one of the most closely watched big data startups in recent years. Founded by the developers of the Apache Spark analytics engine, San Francisco-based Databricks markets the Databricks Lakehouse Platform, its flagship unified data analytics platform.
