Dataset Operations

Learn how to efficiently manage, analyze, and manipulate datasets within TW.

Overview

Dataset Operations provide a comprehensive suite of tools for working with your data. From importing and exporting to advanced analytics and transformations, our platform makes data management simple and powerful.

Key Features

Data Import

Import data from various sources including CSV, JSON, databases, and APIs.

import { DatasetImporter } from '@tw/sdk';

const importer = new DatasetImporter();
await importer.importFromCSV('/path/to/data.csv', {
  delimiter: ',',
  headers: true,
  encoding: 'utf-8'
});

Data Transformation

Apply transformations to clean and prepare your data.

const dataset = await Dataset.load('my-dataset');
await dataset.transform({
  removeNulls: true,
  normalizeFields: ['email', 'phone'],
  convertDates: ['created_at', 'updated_at']
});

Analytics

Run powerful analytics on your datasets to gain insights.

| Operation | Description | Performance | |-----------|-------------|-------------| | Aggregation | Group and summarize data | Fast | | Filtering | Filter rows based on conditions | Very Fast | | Joining | Combine multiple datasets | Moderate | | Pivoting | Reshape data for analysis | Moderate |

Best Practices

  1. Validate Data Early - Always validate your data upon import
  2. Use Batch Operations - Process large datasets in batches for better performance
  3. Monitor Resource Usage - Keep an eye on memory and CPU usage during operations
  4. Implement Error Handling - Always handle potential errors gracefully
