I have an interest in creating a NoSQL database system for a school project and I am curious as to which languages are the different examples of NoSQL database systems are written in. If there is a majority leader, why is that language the favorite? And if there is more involved in the creation, such as different layers (of a stack), that information would be helpful as well.
Thank you.
currently they are mostly written in Java, (Cassandra, Hadoop/HBase etc) but there is nothing that makes writing them in another language harder or impractical. I think the reason is that most of these come from open source background, which is mostly developed in java.
