Based on your specific scenario with 1 source connector and 1 destination connector, both being API connectors, I can provide a more focused estimation. However, it's important to note that the performance can still vary depending on the specific APIs, data volume, and sync frequency. According to the [Scaling Airbyte documentation](
https://docs.airbyte.com/operator-guides/scaling-airbyte), Airbyte's performance is primarily affected by the number of concurrent syncs running at any given time. With only one connection (1 source and 1 destination), you're unlikely to run into scaling issues on an n2-standard-4 GCP VM. Let's consider some potential limitations based on the information provided: 1. API Rate Limits: The main constraint in your case is likely to be the rate limits of the APIs you're connecting to, rather than Airbyte itself. For example, the [Google Sheets API](
https://docs.airbyte.com/integrations/sources/google-sheets#limitations--troubleshooting) has a limit of 300 read requests per minute per project and 60 requests per minute per user per project. 2. Airbyte's Processing: With a single connection, Airbyte should be able to handle a high number of requests per month. The n2-standard-4 configuration (4 vCPUs, 16 GB memory) should be more than sufficient for this workload. Given these factors, here's a rough estimation: - Assuming your APIs allow for frequent syncs, you could potentially run syncs every hour (24 times per day). - This would result in approximately 720 sync jobs per month (24 syncs * 30 days). However, this is a theoretical maximum. In practice, you might sync less frequently, perhaps a few times a day, which would result in 90-180 sync jobs per month (3-6 syncs per day * 30 days). Keep in mind that the actual number of API requests during each sync job depends on the amount of data being transferred and how the specific connectors are implemented. For more accurate estimates, you should: 1. Check the rate limits and quotas for your specific API connectors. 2. Consider the volume of data you're syncing and how often it needs to be updated. 3. Run some test syncs to measure the actual performance and adjust your sync frequency accordingly. Remember, with this setup, you're more likely to be limited by API rate limits than by Airbyte's capacity on the n2-standard-4 VM.
