Azure Data Studio

A data processing and analysis toolkit for querying, importing, exporting, transforming, and validating data. Provides a lightweight CLI interface for common data operations with persistent local storage.

Commands

Data Storage

• Data directory: ~/.local/share/azuredatastudio/ (override with AZUREDATASTUDIO_DIR env variable)
• Data log: $DATA_DIR/data.log — primary data storage file for records
• History log: $DATA_DIR/history.log — tracks all command executions with timestamps

Schema

The default data schema uses the following fields:

Requirements

• Bash 4.0+
• Standard Unix utilities (wc, head, cat, date)
• No API keys or external services needed
• No database server required — uses flat file storage
• Works on Linux and macOS

When to Use

1. Data querying — When you need to run quick queries against your local data store without spinning up a full database
2. File import/export — When you need to import data files into the local store or export records for use in other tools
3. Data validation — When you want to verify your data conforms to the expected schema before processing
4. Data transformation — When you need to convert data between formats (e.g., restructuring fields)
5. Quick statistics — When you want to see basic metrics like total record count or preview sample data at a glance

Examples

# Query data with search terms
azuredatastudio query "SELECT * FROM users WHERE active=1"

# Import a CSV file
azuredatastudio import data.csv

# Export results to a file
azuredatastudio export results.json

# Transform data from one format to another
azuredatastudio transform input.csv output.json

# Validate data against the schema
azuredatastudio validate

# Show basic statistics
azuredatastudio stats

# Display the data schema
azuredatastudio schema

# Preview sample data (first 5 records)
azuredatastudio sample

# Clean and deduplicate data
azuredatastudio clean

# Show a quick dashboard with totals
azuredatastudio dashboard

Output

All command results are printed to stdout. You can redirect output with standard shell operators:

azuredatastudio query "users" > query-results.txt
azuredatastudio export | jq .
azuredatastudio stats >> report.log

Configuration

Set the AZUREDATASTUDIO_DIR environment variable to change the data directory:

export AZUREDATASTUDIO_DIR="/custom/path/to/azuredatastudio"

Default location: ~/.local/share/azuredatastudio/
