For the hubspot connector the initial sync was 30gb in 2 weeks its balloned to 140gb's there isn't any property history turned on, what could be causing it?

Based on the knowledge sources, there are a few potential causes for this kind of data growth with the HubSpot connector, though I should note the sources don't directly address your exact scenario: Possible Causes of Rapid Data Growth 1. Duplicate/Looping Records A known bug introduced in connector versions 5.4.0–5.8.5 caused streams like

contacts

,

tickets

,

line_items

, and

to loop and duplicate records — in some cases fetching data 100x more than expected. [GitHub Issue] > One user reported 1.1 million entries fetched when only ~420k tickets existed, with tickets duplicated 106 times. Fix: This was resolved in v5.8.6/5.8.7. If you're on an affected version, upgrading should stop the runaway growth. 2. Sync Mode Causing Append Growth If you're using Incremental | Append (rather than Incremental | Append + Deduped), every updated record is appended to the destination rather than updated in-place, causing monotonic data growth over time. [Incremental Append Docs] 3. Hidden API Calls Multiplying Data The HubSpot connector makes additional association API calls per page for CRM streams (contacts, deals, etc.), and some streams like Campaigns make one extra API call per record. While this primarily affects API rate limits, it can also contribute to unexpected data volumes. [Contributing Guide] Recommended Steps 1. Check your connector version — if between 5.4.0 and 5.8.5, upgrade to 5.8.7+ immediately. 2. Check your sync mode — switch to Incremental | Append + Deduped if you're using plain Append. 3. Check for duplicate records in your destination to confirm if looping is the cause. The knowledge sources don't contain enough detail to pinpoint your exact cause definitively, so I'd recommend opening a GitHub issue with your connector version and destination details if the above steps don't resolve it. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
