ParamStore

Hierarchical configuration management with dynamic evaluation and versioning.

Overview

ParamStore is the configuration layer of AionixOne, providing AWS Parameter Store-like capabilities for managing application configuration with path-based hierarchy and version history.

TRN Pattern

trn:paramstore:{tenant}:param/{path}

Key Features

• Path Hierarchy — Organize parameters like /app/db/host, /app/db/port
• Multiple Types — String, number, boolean, JSON, secret reference
• Dynamic Evaluation — Expression evaluation at read time
• Versioning — Full version history with rollback
• DSL Integration — Reference via $param.{path} syntax in workflows

Quick Example

# Set parameters
aio param set /app/config/timeout --value 30
aio param set /app/db/host --value "localhost"
aio param set /app/db/port --value 5432 --type number
 
# Get parameter
aio param get /app/config/timeout
 
# List by path prefix
aio param list /app/db
 
# Get with history
aio param history /app/config/timeout

DSL Reference

In StepFlow workflows:

{
  "parameters": {
    "timeout": "{% $param('/app/config/timeout') %}",
    "dbHost": "{% $param('/app/db/host') %}"
  }
}
