Mida täpselt saatsite, et Avito kuulutuste avaldamise ja haldamise teenus muutuks kiirem?

To accelerate the ad publishing and management service on Avito, the following can be done:

• Caching: cache frequently requested data (e.g., ad statuses) in memory or Redis to reduce database load.
• Asynchronous processing: separate ad publication from heavy operations (e.g., indexing or notifications) using a message queue.
• Database query optimization: add indexes, use efficient queries, minimize the number of requests.
• Parallelism and goroutines: use goroutines for parallel processing of requests and background tasks.
• Data compression and minimization: reduce the volume of data transmitted between services.
• Monitoring and profiling: identify bottlenecks and optimize them.

Example code using goroutines for parallel publication processing:

func PublishAd(ad Ad) error {
    // Start asynchronous index update
    go func() {
        err := updateSearchIndex(ad)
        if err != nil {
            log.Println("Index update failed:", err)
        }
    }()
    // Main publication logic
    err := saveAdToDB(ad)
    return err
}
