Learn how to design Solana programs using account segregation patterns to improve parallelization, reduce contention, and enhance scalability.

Overview

Solana's parallel execution engine (Sealevel) processes transactions simultaneously when they operate on different accounts. To maximize throughput, developers need to carefully design their account structures to minimize contention. This tutorial explores account segregation patterns to optimize Solana program performance.

Key topics covered:

• Understanding how account access patterns affect parallelization
• Avoiding the "hot account" problem that leads to serialization
• Implementing counter segregation for high-frequency metrics
• Using two-phase commits for atomic operations across multiple accounts
• Building sharded data structures for high-concurrency applications
• Measuring and optimizing transaction throughput
• Real-world examples of account segregation in DeFi and NFT applications

Account segregation is essential for building high-performance Solana applications. These patterns will help you design programs that can fully utilize Solana's parallelized transaction processing for maximum throughput and efficiency.
