What I am askign is if I upgrade snowflaek destination 4.0.43 to 4.0.45 in aribyte then will it break any exsiitng onnections in airbyte or create any issues?

Based on the knowledge sources, upgrading from destination-snowflake 4.0.43 to 4.0.45 involves two patch-level fixes. Here's what changed and whether it could break anything: Changes Between 4.0.43 → 4.0.45 4.0.43 → 4.0.44 (two fixes rolled up) 1. Reserved column name collision fix – Users syncing records with columns named

_airbyte_meta

,

_airbyte_raw_id

, etc. will now see those user columns auto-renamed instead of hitting duplicate-column errors. [CDK upgrade PR] 2. Permission error classification fix – Snowflake permission errors (e.g., "Insufficient privileges to operate on schema") are now correctly classified as config errors instead of system errors, avoiding unnecessary retries and Sentry alerts. [Permission fix PR] 4.0.44 → 4.0.45 3. NULL-safe PK matching restored in dedup MERGE – A regression introduced in 4.0.44 broke Append+Dedup syncs where composite primary keys contained NULL values, causing rows to be re-inserted on every sync (unbounded duplication). This fix restores correct deduplication behavior. [NULL-safe PK fix] Will It Break Existing Connections? No breaking changes are introduced. All three fixes are: • Patch-level version bumps (not major/minor) • Explicitly marked as non-breaking and safely reversible • No changes to stream schemas, field types, primary keys, cursors, connector configuration, or state format In fact, staying on 4.0.43 carries more risk than upgrading: • You'd be exposed to the dedup regression bug (unbounded row duplication for NULL composite PKs) that was introduced in 4.0.44 and fixed in 4.0.45. Recommendation: Upgrade to 4.0.45. It is safe and actually fixes data-correctness issues present in 4.0.43 and 4.0.44. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
