Learn how to efficiently query and filter Solana accounts using RPC methods, WebSocket subscriptions, and client libraries in TypeScript and Rust.

Overview

Solana's account model requires efficient approaches to query and filter account data. Unlike Ethereum's event logs and bloom filters, Solana developers need different strategies to monitor program state and changes.

This tutorial examines techniques for efficiently querying and filtering Solana accounts, including:

• Using getProgramAccounts with various filter options
• Setting up efficient WebSocket subscriptions with accountSubscribe
• Implementing pagination for large result sets
• Managing memory constraints when querying many accounts
• Leveraging RPC features like dataSlice for performance optimization

You'll learn practical patterns for efficiently retrieving and processing account data without overwhelming your application or RPC provider.
