Incremental models duplicate keys when the unique_key does not match the real grain or when late data bypasses the merge: inspect the duplicates the run created, confirm the unique_key columns in the model configuration, and rebuild the affected window with a correct merge.

Vectle found the following relevant skills: - dbt incremental merge failed: cannot merge on column of type variant - agent cannot parse new hire spreadsheet with merged cells: parsing failed with error and the workflow broke

Fixes the cost and correctness fallout when a generated dbt model lands with the wrong materialization, such as a full table rebuild of a huge model or a view where a table was needed, covering materialization review and config guardrails. Use when a merged model change spikes warehouse spend. Not for a model whose co…
Handles a merge failure when a source that was expected to send changes sends a full snapshot instead, covering snapshot detection, load mode switching, and protecting the target from a bad merge. Use when a full extract lands in an incremental path. Not for a designed full refresh that the pipeline schedules delibera…
Fixes the aftermath and prevents recurrence of an agent running dbt with --full-refresh against prod, wiping incremental history. Use when a full refresh hit a production incremental or snapshot-adjacent table. Not for planned full refreshes during migrations.
Fixes the damage and root cause after an agent dropped unique_key from an incremental model config, forcing full table rescans or duplicate prone appends. Use when an incremental model lost its unique_key. Not for models designed as append-only.
Shows how to analyse a dbt project without feeding the whole manifest file to an agent, using targeted extraction of nodes, a summary index, and the manifest's own structure. Use when manifest based analysis dies on context size. Not for a manifest that is corrupt and will not parse at all.
Covers recovering from an agent rerunning a partial load so already loaded rows are written twice, including finding the duplicate window, deduplicating safely, and making the load idempotent. Use when a retry has duplicated data in the warehouse. Not for duplicates caused by a source that itself sends repeated record…
Fixes incremental merge models that keep duplicating rows instead of deduplicating on unique_key. Use when row counts grow on every run with repeated keys. Not for append models, which duplicate by design.
Vectle found the following relevant skills: - dbt incremental model full refresh failed: unique key collision - dbt incremental merge failed: cannot merge on column of type variant

Public search query: dbt incremental model merge not deduplicating: duplicate rows keep growing

Fixes the silent empty table outcome where dbt run succeeds but the Snowflake table has no rows. Use when the built table exists, the run is green, and selects return zero rows. Not for failed runs or missing tables.
Vectle found the following relevant skills: - snowflake table swap failed during dbt run - dbt grants error: not applying to new tables in snowflake - [dbt run error: None…

Fixes a dbt snapshot that misses hard deletes, covering the check strategy versus timestamp strategy, invalidate_hard_deletes, and sources that physically remove rows. Use when deleted source rows stay current in the snapshot. Not for soft deletes that arrive as an updated flag.
Fixes a dbt incremental merge that fails on Snowflake because the unique key or a compared column is a VARIANT, covering casting the key, flattening semi-structured data, and merge strategy choice. Use when the merge statement errors on a variant column. Not for a plain type mismatch between two scalar columns.

Fixes a dbt BigQuery model that fails because its configured timestamp partition field is not in the model output, covering partition_by config, column naming, and data type. Use when BigQuery rejects the model create or merge. Not for a clustering only model with no partitioning.
Fixes a dbt incremental model whose full refresh fails on its unique key, because the source itself contains duplicate keys or the merge key is not actually unique. Use when a full refresh fails on an incremental model. Not for a normal incremental run that merges cleanly.
Vectle found the following relevant skills: - dbt incremental model broken: re-running full refresh every time - dbt test failed: schema mismatch on incremental model - [U…
