In modern business operations, specialized tools are essential. Salesforce often serves as the central repository for customer data, while teams leverage Airtable for its unparalleled flexibility in project management, operational workflows, and as an agile database.

The critical challenge lies in ensuring data flows seamlessly between them. When this connection isn't instantaneous, workflows break, and teams are forced to work with outdated information.

Many organizations initially turn to data integration tools like Fivetran, only to encounter frustrating data lags that disrupt operations. This article explains why the Fivetran real-time data sync from Salesforce to Airtable is often not real-time at all and introduces a purpose-built, bi-directional solution with Stacksync to eliminate latency and power your workflows.

The Problem with Fivetran's "Near" Real-Time Sync

Fivetran is a widely adopted data integration platform, and for good reason—it excels at its primary function: moving data from various sources into data warehouses for analytics. Its architecture is fundamentally based on batch processing, which involves collecting changes and moving them in scheduled intervals.

While Fivetran has introduced a "1-minute sync" capability, it's crucial to recognize this is not true real-time [1]. For an analytics dashboard that's reviewed periodically, a delay of a few minutes might be perfectly acceptable.

However, for operational use cases, like a sales deal updated in Salesforce needing to instantly kick off a project in Airtable—even a one-minute gap means teams are working with stale data. This latency can lead to manual reconciliation, missed steps, and operational inefficiency.

Why Does Fivetran Lag When Syncing Salesforce to Airtable?

The sync delays experienced with Fivetran are not a bug but a direct consequence of its batch-oriented ETL/ELT design. This architectural choice is optimal for large-scale analytical data loads but creates an inherent operational data gap. As we've analyzed in our breakdown of traditional ETL platforms vs. real-time sync, the reasons for this lag are systemic.

Here are the common technical factors causing Fivetran sync delays with Salesforce:

• Batch Overlaps & Scheduling: Data is moved on a fixed schedule (e.g., every one, five, or fifteen minutes). By design, the data in your destination is always lagging behind the source.
• API Rate Limits: Salesforce imposes strict API call limits to protect platform stability. A batch process like Fivetran's can consume a large number of calls in a short burst, causing it to hit these limits and get throttled, which pauses or delays the sync [2].
• Data Volume Spikes: A mass record update in Salesforce, such as a large data import or a campaign update, creates a significant data queue. Fivetran must process this entire batch before it can sync newer changes, resulting in extended lag times.
• Incremental Complexity: Identifying changed data in Salesforce often relies on fields like SystemModStamp. The logic to query and process these changes incrementally can become slow and complex, particularly with large data volumes.

These issues are well-documented, with many Fivetran users seeking ways to troubleshoot sync delays [3]. This confirms that for operational needs, the problem isn't a faulty tool but a mismatch between the tool's architecture and the job at hand.

The Solution: True Real-Time, Two-Way Sync with Stacksync

For operational workflows that demand immediate data consistency, a different architectural approach is required. Stacksync is a modern data integration platform engineered specifically for real-time, operational use cases. Instead of batch processing, Stacksync uses an event-driven architecture that captures and propagates changes the moment they occur.

The core differentiator is true bi-directional synchronization. As detailed in the definitive guide to two-way sync, this technology means updates in Salesforce appear in Airtable instantly. Furthermore, if configured, changes made in Airtable can be securely synced back to Salesforce, keeping both systems operating as a single, cohesive unit.

Key advantages of Stacksync's approach include:

• Sub-second Latency: Data is synchronized in near real-time, typically under five seconds, eliminating the operational data gap.
• Bi-Directional Flow: Keeps both systems perfectly aligned, allowing teams to work in their preferred application without creating data conflicts.
• Built for Operations: Our platform is designed from the ground up to power live business workflows, not just populate analytics reports.

Stacksync vs. Fivetran: A Direct Comparison for Salesforce & Airtable

Choosing the right integration tool requires understanding its intended purpose. While Fivetran is a powerful platform, it is not interchangeable with a real-time operational tool like Stacksync. Our direct comparison of Stacksync, Fivetran, and other tools makes the distinction clear.

Here is how the two platforms stack up for a Salesforce-to-Airtable sync:

Data Latency

• Fivetran: Moves data on a schedule. Your data in Airtable is always lagging behind what's current in Salesforce.
• Stacksync: Moves data the moment a change occurs. Your teams in Airtable always work with live data.

Sync Directionality

• Fivetran: Data flows in one direction from a source to a destination. This is standard for ETL tools designed for data loading.
• Stacksync: Data can flow back and forth between systems. This ensures perfect alignment and empowers teams to update data in either tool. You can see this in action when you sync Airtable and Close or any other combination of our 200+ connectors.

Primary Use Case

• Fivetran: Built for analytics. It excels at loading data into a warehouse like Snowflake or BigQuery for reporting, as evidenced by its focus on database replication for downstream analysis [4] [4].
• Stacksync: Built for operations. It is designed for connecting SaaS applications so teams can automate processes and act on live information without delay.

Stop Compromising and Sync Data in Real Time

While Fivetran is a highly capable tool for its intended purpose—data warehousing—its batch architecture makes it fundamentally unsuited for the real-time operational demands of syncing Salesforce to Airtable. The sync lag it produces is a direct cause of broken automation, inefficient team collaboration, and poor decisions made on stale data.

Don't let your integration tool become a bottleneck. Stacksync provides the purpose-built, real-time solution to eliminate these issues and achieve true data consistency across your applications. Empower your teams with live, actionable data so your business can operate at its full potential.
