NoSQL databases
We have already discussed about NoSQL as one of the emerging and adopted systems. Within Hadoop ecosystem, we have a NoSQL database called HBase. HBase is one of the key component that provides a very flexible design and high volume simultaneous reads and write in low latency hence it is widely adopted.
Apache HBase
HBase is inspired from Google's Big Table. HBase is a sorted map, which is sparse, consistent, distributed, and multidimensional. HBase is a NoSQL, column oriented database and a key/value store, which works on top of HDFS. HBase provides faster lookup and also high volume inserts/updates of a random access request on a high scale.
