Cassandra Cqlsh (Cassandra Query Language shell) is a command-line interface that allows users to interact with the Apache Cassandra database system. It provides a way to execute Cassandra Query Language (CQL) statements, which is the primary language used to interact with the Cassandra database.
Cqlsh provides a user-friendly interface to create, read, update, and delete data from the Cassandra database. It allows developers to interact with the database without the need for a graphical user interface or a web-based console. Cqlsh is included with the Cassandra distribution and can be installed and run on any machine that has access to the Cassandra cluster.
The Cqlsh interface provides a variety of features, including command-line autocompletion, syntax highlighting, and support for multiple CQL versions. It allows developers to execute queries against the Cassandra database, create and modify tables, and manage the database schema.
In addition to executing queries, Cqlsh also provides access to Cassandra’s system tables, which store metadata about the database and its objects. These tables can be queried to obtain information about the database, such as the list of keyspaces and the properties of individual tables.
Overall, Cqlsh provides a powerful tool for developers to interact with the Cassandra database system, allowing for efficient management and manipulation of data.
