⚡ Improved Sync Webhook Latency on the Cloud - Part 2

Hi Everyone,

One of my first tasks was improving webhook sync latency.

Improved Sync Webhook Latency on the Cloud

Hi Everyone, Update: We have stabilized the latency of the sync webhooks on the cloud. What was happening: Previously, the first call of the flow used to be very slow because it started caching. This happened multiple times a day due to multiple deployments and the cache was cleared after. What we did: We now save the cache across deployments. Result: The latency of the /sync webhooks should be consistent across requests, no more cold boot. T…

What was happening:

• Webhooks were slow because execution needed two hops through queues to start execution.
• Flows were loaded from the database every time, causing delays.

What we did:

• Optimized execution in a single step (no extra hops).
• Cached flows in memory to avoid loading them from the database every time.

Result:

• Cloud (SANDBOXED): latency dropped from ~4s ➔ 1–2s.
• Self-Hosted (SANDBOX_CODE_ONLY): latency dropped from ~1100ms ➔ 100–200ms.

Now, /sync webhooks are much faster and more stable!

Thank you!
