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 multi-threaded 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
