A Kudu cluster organizes its data into tables, which resemble the tables found in traditional relational (SQL) databases. These tables can range from straightforward binary key-value pairs to intricate structures featuring hundreds of distinct, strongly-typed attributes. Similar to SQL databases, each table has a primary key composed of one or more columns, which could be a singular column, such as a unique user ID, or a composite key like a tuple of (host, metric, timestamp) typically used in machine time-series databases. Rows can be quickly accessed, modified, or removed using their primary key, ensuring efficient data management. The straightforward data model of Kudu facilitates the migration of legacy systems or the creation of new applications without the hassle of encoding data into binary formats or deciphering complex databases filled with difficult-to-read JSON. Additionally, the tables are self-describing, allowing users to leverage common tools such as SQL engines or Spark for data analysis tasks. The user-friendly APIs provided by Kudu further enhance its accessibility for developers. Overall, Kudu streamlines data handling while maintaining a robust structure.
