Big Data is a culmination of numerous research and DEVELOPMENT projects at IBM. So IBM has taken the work from these various projects and released it as a technology preview called Big SQL.

IBM claims that Big SQL provides robust SQL support for the Hadoop ecosystem:

• it has a scalable architecture
• it supports SQL and data types available in SQL '92, plus it has some additional capabilities
• it supports JDBC and ODBC client drivers
• it has efficient handling of "POINT queries"

Big SQL is based on a multi­threaded architecture, so it's good for performance and the scalability in a Big SQL environment essentially depends on the Hadoop cluster itself that is its size and scheduling POLICIES.
