Concurrency best practices for large data volumes

In an iPaaS, concurrency is the platform’s ability to execute multiple tasks, processes, or workflows simultaneously. This enables integrations to run in parallel, efficiently managing overlapping operations such as concurrent API calls and large data transfers. By dividing workloads into smaller, parallel units, concurrency enhances performance, speeds up processing, and optimizes resource utilization.

Think of concurrency like a highway system. Without it, data moves along a single-lane road, forcing each task to wait for the one ahead, leading to slowdowns and bottlenecks. With concurrency, the system expands into a multi-lane highway, allowing multiple processes to run simultaneously, reducing congestion and improving speed. Just as traffic signals optimize vehicle flow, concurrency ensures efficient resource allocation, keeping integrations running smoothly without unnecessary delays.

Managing concurrency is critical for high-volume data processing. The right configuration speeds up data synchronization, prevents API throttling, and ensures consistent performance. Poorly managed concurrency, on the other hand, leads to delays, resource limits, and missed SLAs.

Here, we’ll explore how Celigo’s tools help you configure, monitor, and scale concurrency settings to keep your integrations fast, efficient, and reliable—even under heavy workloads.

Key benefits of concurrency management

1. Enhanced performance and speed
   Processing tasks in parallel significantly reduces workflow completion times.
   • Example: Syncing 10,000 records with concurrency set to five threads can be five times faster than processing one record at a time.
2. Improved scalability
   Concurrency ensures systems can handle growing data volumes without performance degradation, adapting to the demands of scaling businesses.
3. Reduced latency for time-sensitive workflows
   Processes like inventory synchronization or payment processing benefit from concurrency by minimizing delays and meeting real-time requirements.
4. Optimized resource utilization
   Concurrency ensures efficient use of system resources, minimizing idle time and maximizing throughput.
5. Support for complex workflows
   Concurrent processing enables businesses to handle interdependent tasks, such as syncing parent and child records, without bottlenecks.
6. Compliance with API governance
   Configuring concurrency appropriately helps avoid exceeding API rate limits, prevent throttling errors, and maintain consistent system performance.

Examples of concurrency in an iPaaS

• Ecommerce order processing
  Concurrency allows multiple customer orders to be processed simultaneously, syncing with an ERP system in parallel. This prevents bottlenecks and ensures timely order fulfillment, even during peak sales periods.
• Real-time inventory updates
  Concurrency enables parallel API calls across multiple platforms (ERP, marketplaces, and warehouse management systems), significantly reducing the time required to update stock levels in real-time and preventing overselling and discrepancies.
• Employee onboarding automation
  When a new employee is hired, concurrency allows multiple onboarding tasks (such as account creation, payroll setup, and software access provisioning) to be processed simultaneously across different systems, accelerating the onboarding experience and reducing manual delays.

Core principles of concurrency in iPaaS

• Parallel process execution
  Execute multiple workflows or tasks simultaneously while efficiently managing resources to prevent contention and performance degradation.
• Dynamic workload scaling
  Automatically scale workloads up or down in response to demand, leveraging cloud-based architectures to optimize resource allocation for concurrent processes.
• Error management and resilience
  Isolate and handle errors within concurrent processes independently, preventing failures from cascading and ensuring uninterrupted workflow execution.
• Throughput and latency optimization
  Maximize data throughput while minimizing latency to maintain high-speed, efficient processing, even under heavy concurrent workloads.

Best practices for managing large data volumes

Optimize flow design

• Partition data intelligently: Break down large datasets into logical segments (e.g., geographic regions, product categories) to enable parallel processing and reduce load on individual API calls.
• Use prebuilt templates: Leverage Celigo’s preconfigured templates to streamline integration setup for common use cases.
• Example: Partitioning order data by region (e.g., North America, EMEA, APAC) helps distribute processing load, reduces API throttling risks, and improves overall runtime efficiency.

Configure concurrency settings effectively

Tailor concurrency settings to align with system capacity and API rate limits to optimize performance.

Steps to configure:

1. Review API rate limits and thresholds: Check API documentation for rate limits, batch processing capabilities, and recommended concurrency settings.
2. Set connection concurrency: Configure concurrency levels to match the API’s processing capacity without exceeding limits.
3. Validate in a sandbox:  Test configurations in a non-production environment to prevent disruptions in live operations.

Enable delta data processing

Delta processing improves efficiency by syncing only modified or newly created records, reducing API usage and processing time.

How to configure:

1. Create a filter:  Define conditions to extract only records updated since the last successful sync.
2. Activate delta processing:  Enable delta settings in the flow configuration to track and process incremental changes.
3. Validate results:  Compare synced records against source logs to confirm accuracy.

Monitor and scale dynamically

• Use Celigo’s monitoring tools to track key performance metrics such as execution time, error rates, and throughput.
• Scale runtime resources dynamically based on data volume fluctuations, ensuring smooth operations during peak loads.

Leverage parallel flows

• Running datasets through multiple concurrent flows reduces runtime while maintaining system stability.
  • Example: Instead of processing all inventory data in a single flow, split it by product categories (e.g., electronics, apparel) to prevent bottlenecks and improve processing speed.

Celigo’s approach to concurrency

Celigo provides powerful tools to configure, monitor, and scale workflows, delivering reliable performance even under high-volume demands.

Key features include:

Dynamic paging and parallel processing

• What it does: Divides large datasets into smaller, manageable chunks for parallel execution, reducing processing time and system strain.
• Benefits: Optimizes API efficiency, minimizes load on target systems, and improves data throughput.
• Example: Adjusting Salesforce SOQL query page sizes to 200–1000 records balances performance while preventing timeouts and API rate limit violations.

AI-powered optimizations

• Predictive monitoring: AI continuously analyzes historical and real-time data to detect anomalies and suggest proactive adjustments, preventing issues like API throttling.
  • Example: If API usage nears rate limits, Celigo recommends reducing thread counts or increasing throttle delays to maintain smooth processing.
• Dynamic scaling insights: AI optimizes key settings such as page sizes, thread counts, and throttle delays based on actual workload patterns, ensuring workflows automatically adapt to peak loads.

Built-in exception management

• Automated retries: Resolves transient errors  (e.g., timeouts, temporary API outages) without manual intervention.
  • Example: A network outage triggers automatic retries, preventing workflow disruptions.
• Detailed error logs: Captures persistent issues (e.g., invalid credentials, permission errors) for manual review.
• Tagging and assignment: Classifies exceptions by type and assigns them to the appropriate team members for faster resolution.

Connection-level concurrency controls

• What it does: Configures concurrent API requests to maximize throughput while preventing throttling.
• Example: If an API has a 60-requests-per-minute limit, Celigo can limit concurrency to 5 requests with a 1-second throttle delay, ensuring efficient and compliant execution.
