KUDU Database

#What is KUDU?

Kudu is an open-source distributed columnar storage engine developed by Cloudera, and it’s designed to work with Apache Hadoop, providing a combination of fast analytics on fast data with SQL and real-time applications. Kudu stores data in columns rather than rows, which provides better performance for analytics queries that read many columns of data.

#KUDU Key Features

Here are some of the most recognizable features of Kudu:

• Is a high-performance columnar storage engine that provides extremely fast random and sequential reads and writes.
• Is designed to work seamlessly with Apache Impala, Apache Spark, and other Hadoop ecosystem tools, providing a flexible and scalable solution for big data processing and analytics.
• Provides a powerful and flexible API for data access, with support for Java, C++, Python, and other programming languages.
• Is highly available and fault-tolerant, with automatic data replication and failover capabilities that ensure data is always available and protected.
• Supports distributed transactions, allowing multiple clients to update the same data atomically and consistently.
• Provides strong security and authentication features, with support for Kerberos and LDAP authentication, encryption of data in transit and at rest, and fine-grained access control.
