gcqlsh

Cassandra command line shell written in Golang

Motivation

Having a cassandra command line shell utility in one binary distributable.

Where it comes in hand?

• Building docker images for cassandra from Alpine with no Python.
• Running cql shell on all platforms.
• Automating cassandra schema creation without need to install python dependencies.

Building

go build -o gocqlsh src/github.com/npenkov/gcqlsh/cmd/gcqlsh.go

Fatures

• Running DDL script files from command line
• Support for Cassandra 2.1+/ScyllaDB
• CQL Support
• Statement tracing
• desc command with
  • keyspaces - simple list
  • tables - simple list
  • table - simple list of columns and types
• Auto completition for commands:
  • use - keyspaces
  • desc - tables
  • select - tables
  • update - tables and columns
  • delete - tables
  • insert - tables

Still missing

• Paging in interactive results
• DDL Statements when describing Keyspaces and tables
• Expanded rows
• Code assistance for different keyspaces
• Node token awareness
