The S2 CLI is a command-line tool for interacting with the S2 stream store. It provides comprehensive management of basins, streams, access tokens, and records, along with benchmarking and monitoring capabilities.

​
Installation

The S2 CLI is distributed as a standalone binary: 
# Download and install the latest version
curl -fsSL https://install.s2.dev | sh

# Verify installation
s2 --version

​
Quick start

Configure your access token: 
s2 config set access_token YOUR_ACCESS_TOKEN
List available basins: 
s2 list-basins
Create a basin and stream: 
s2 create-basin my-basin
s2 create-stream s2://my-basin/events

​
Command structure

The CLI follows a hierarchical command structure: 
s2 [COMMAND] [SUBCOMMAND] [OPTIONS] [ARGUMENTS]

​
Common patterns

S2 URIs - Most stream operations use the format s2://{basin}/{stream}: 
s2 append s2://my-basin/events
s2 read s2://my-basin/events
s2 delete-stream s2://my-basin/events
Listing with filters - Support prefix filtering and pagination: 
s2 list-basins --prefix "prod" --limit 100
s2 list-streams my-basin --prefix "events/" --start-after "events/2024"
Output formats - Record operations support multiple formats: 
s2 read s2://basin/stream --format text
s2 read s2://basin/stream --format json
s2 read s2://basin/stream --format json-base64

​
Command categories

​
Basin management

  • list-basins - List all basins
  • create-basin - Create a new basin
  • delete-basin - Delete a basin
  • get-basin-config - View basin configuration
  • reconfigure-basin - Update basin settings

​
Stream management

  • list-streams - List streams in a basin
  • create-stream - Create a new stream
  • delete-stream - Delete a stream
  • get-stream-config - View stream configuration
  • reconfigure-stream - Update stream settings
  • check-tail - Check the tail position of a stream

​
Record operations

  • append - Append records to a stream
  • read - Read records from a stream
  • tail - Show the last N records (like Unix tail)

  • get-stream-metrics - Retrieve stream-level metrics

​
Utilities

  • ls - List basins or streams (convenience command)
  • apply - Apply declarative spec files
  • bench - Run performance benchmarks
  • lite - Run local S2 Lite server

​
Interactive mode

Launch the interactive TUI (Terminal User Interface): 
s2 -i
# or
s2 --interactive
The TUI provides a visual interface for browsing basins and streams.

​
Global options

s2 --help              # Show help for any command
s2 --version           # Display CLI version

​
Environment variables

All configuration values can be set via environment variables with the S2_ prefix: 
export S2_ACCESS_TOKEN="your-token"
export S2_ACCOUNT_ENDPOINT="https://account.s2.dev"
export S2_BASIN_ENDPOINT="https://basin.s2.dev"
export S2_COMPRESSION="zstd"
export S2_SSL_NO_VERIFY="false"
Environment variables override configuration file values.

​
Exit codes

  • 0 - Success
  • 1 - General error
  • 2 - Invalid arguments or usage
