Design the unique_key carefully. Handle edge cases.**\n\n## When to Use Incremental\n\n| Scenario | Recommendation |\n|----------|----------------|\n| Source data < 10M rows | Use `table` (simpler, full refresh is fast) |\n| Source data > 10M rows | Consider `incremental` |\n| Source data updated in place | Use `incremental` with `merge` strategy |\n| Append-only source (logs, events) | Use `incremental` with `append` strategy |\n| Partitioned warehouse data | Use `insert_overwrite` if supported |\n\n**Default to `table` unless you have a clear performance reason for incremental.**\n\n## Critical Rules\n\n1. **ALWAYS test with `--full-refresh` first** before relying on incremental logic\n2. **ALWAYS verify unique_key is truly unique** in both source and target\n3. **If merge fails 3+ times**, check unique_key for duplicates\n4. **Run full refresh periodically** to prevent data drift\n\n## Workflow\n\n### 1. Confirm Incremental is Needed\n\n```bash\n# Check source table size\ndbt show --inline \"select count(*) from {{ source('schema', 'table') }}\"\n```\n\nIf count < 10 million, consider using `table` instead. Incremental adds complexity.\n\n### 2. Understand the Source Data Pattern\n\nBefore choosing a strategy, answer:\n- **Is data append-only?** (new rows added, never updated)\n- **Are existing rows updated?** (need merge/upsert)\n- **Is there a reliable timestamp?** (for filtering new data)\n- **What's the unique identifier?** (for merge matching)\n\n```bash\n# Check for timestamp column\ndbt show --inline \"\n select\n min(updated_at) as earliest,\n max(updated_at) as latest,\n count(distinct date(updated_at)) as days_of_data\n from {{ source('schema', 'table') }}\n\"\n```\n\n### 3. Choose the Right Strategy\n\n| Strategy | Use When | How It Works |\n|----------|----------|--------------|\n| `append` | Data is append-only, no updates | INSERT only, no deduplication |\n| `merge` | Data can be updated | MERGE/UPSERT by unique_key |\n| `delete+insert` | Data updated in batches | DELETE matching rows, then INSERT |\n| `insert_overwrite` | Partitioned tables (BigQuery, Spark) | Replace entire partitions |\n\n**Default:** `merge` is safest for most use cases.\n\n**Note:** Strategy availability varies by adapter. Check the [dbt incremental strategy docs](https://docs.getdbt.com/docs/build/incremental-strategy) for your specific warehouse.\n\n### 4. Design the Unique Key\n\n**CRITICAL: unique_key must be truly unique in your data.**\n\n```bash\n# Verify uniqueness BEFORE creating model\ndbt show --inline \"\n select {{ unique_key_column }}, count(*)\n from {{ source('schema', 'table') }}\n group by 1\n having count(*) > 1\n limit 10\n\"\n```\n\nIf duplicates exist:\n- Add more columns to make composite key\n- Add deduplication logic in model\n- Use `delete+insert` instead of `merge`\n\n### 5. Write the Incremental Model\n\n```sql\n{{\n config(\n materialized='incremental',\n incremental_strategy='merge', -- or append, delete+insert\n unique_key='id', -- MUST be unique\n on_schema_change='append_new_columns' -- handle new columns\n )\n}}\n\nselect\n id,\n column_a,\n column_b,\n updated_at\nfrom {{ source('schema', 'table') }}\n\n{% if is_incremental() %}\nwhere updated_at > (select max(updated_at) from {{ this }})\n{% endif %}\n```\n\n### 6. Build with Full Refresh First\n\n**ALWAYS verify with full refresh before trusting incremental logic.**\n\n```bash\n# First run: full refresh to establish baseline\ndbt build --select --full-refresh\n\n# Verify output\ndbt show --select --limit 10\ndbt show --inline \"select count(*) from {{ ref('model_name') }}\"\n```\n\n### 7. Test Incremental Logic\n\n```bash\n# Run incrementally (no --full-refresh)\ndbt build --select \n\n# Verify row count changed appropriately\ndbt show --inline \"select count(*) from {{ ref('model_name') }}\"\n```\n\n### 8. Handle Schema Changes\n\nSet `on_schema_change` based on your needs:\n\n| Setting | Behavior |\n|---------|----------|\n| `ignore` (default) | New columns in source are ignored |\n| `append_new_columns` | New columns added to target |\n| `sync_all_columns` | Target schema matches source exactly |\n| `fail` | Error if schema changes |\n\n## Common Incremental Problems\n\n### Problem: Merge Fails with Duplicate Key\n\n**Symptom:** \"Cannot MERGE with duplicate values\"\n\n**Cause:** Multiple rows with same unique_key in source or target.\n\n**Fix:**\n```sql\n-- Add deduplication using a CTE (cross-database compatible)\nwith deduplicated as (\n select *,\n row_number() over (partition by id order by updated_at desc) as rn\n from {{ source('schema', 'table') }}\n {% if is_incremental() %}\n where updated_at > (select max(updated_at) from {{ this }})\n {% endif %}\n)\nselect * from deduplicated where rn = 1\n```\n\n### Problem: No Partition Pruning (Full Table Scan)\n\n**Symptom:** Incremental runs take as long as full refresh.\n\n**Cause:** Dynamic date filter prevents partition pruning.\n\n**Fix:**\n```sql\n{% if is_incremental() %}\n-- Use static date instead of subquery for partition pruning\nwhere updated_at >= {{ dbt.dateadd('day', -3, dbt.current_timestamp()) }}\n and updated_at > (select max(updated_at) from {{ this }})\n{% endif %}\n```\n\n### Problem: Late-Arriving Data is Missed\n\n**Symptom:** Some records never appear in incremental model.\n\n**Cause:** Filtering by max(updated_at) misses late arrivals.\n\n**Fix:** Use a lookback window with a fixed offset from current date:\n```sql\n{% if is_incremental() %}\n-- Lookback 3 days to catch late-arriving data\nwhere updated_at >= {{ dbt.dateadd('day', -3, dbt.current_timestamp()) }}\n{% endif %}\n```\n\nAlternatively, use a variable for the lookback period:\n```sql\n{% set lookback_days = 3 %}\n\n{% if is_incremental() %}\nwhere updated_at >= {{ dbt.dateadd('day', -lookback_days, dbt.current_timestamp()) }}\n{% endif %}\n```\n\n### Problem: Schema Drift Causes Errors\n\n**Symptom:** \"Column X not found\" after source adds column.\n\n**Fix:** Set `on_schema_change='append_new_columns'` in config.\n\n### Problem: Data Drift Over Time\n\n**Symptom:** Counts diverge between incremental and full refresh.\n\n**Fix:** Schedule periodic full refresh:\n```bash\n# Weekly full refresh\ndbt build --select --full-refresh\n```\n\n## Incremental Strategy Reference\n\n### Append (Simplest)\n\n```sql\n{{ config(materialized='incremental', incremental_strategy='append') }}\n\nselect * from {{ source('events', 'raw') }}\n{% if is_incremental() %}\nwhere event_timestamp > (select max(event_timestamp) from {{ this }})\n{% endif %}\n```\n\n- No unique_key needed\n- Fastest performance\n- **Only use for append-only data** (logs, events, immutable records)\n\n### Merge (Default)\n\n```sql\n{{ config(\n materialized='incremental',\n incremental_strategy='merge',\n unique_key='id'\n) }}\n\nselect * from {{ source('crm', 'contacts') }}\n{% if is_incremental() %}\nwhere updated_at > (select max(updated_at) from {{ this }})\n{% endif %}\n```\n\n- Requires unique_key\n- Handles updates and inserts\n- Most common strategy\n\n### Delete+Insert (Batch Updates)\n\n```sql\n{{ config(\n materialized='incremental',\n incremental_strategy='delete+insert',\n unique_key='id'\n) }}\n\nselect * from {{ source('orders', 'raw') }}\n{% if is_incremental() %}\nwhere order_date >= {{ dbt.dateadd('day', -7, dbt.current_timestamp()) }}\n{% endif %}\n```\n\n- Deletes all matching rows first\n- Good for reprocessing batches\n- Use when merge has duplicate key issues\n\n### Insert Overwrite (Partitioned)\n\n```sql\n{{ config(\n materialized='incremental',\n incremental_strategy='insert_overwrite',\n partition_by={'field': 'event_date', 'data_type': 'date'}\n) }}\n\nselect * from {{ source('events', 'raw') }}\n{% if is_incremental() %}\nwhere event_date >= {{ dbt.dateadd('day', -3, dbt.current_timestamp()) }}\n{% endif %}\n```\n\n- Replaces entire partitions\n- Best for partitioned tables in BigQuery/Spark\n- No unique_key needed (operates on partitions)\n\n## Anti-Patterns\n\n- Using incremental for small tables (< 10M rows)\n- Not testing with full-refresh first\n- Using append strategy when data can be updated\n- Not verifying unique_key uniqueness\n- Relying on exact timestamp match without lookback\n- Never running full refresh (causes data drift)\n- Using merge with non-unique keys\n\n## Testing Checklist\n\n- [ ] Model runs with `--full-refresh`\n- [ ] Model runs incrementally (without flag)\n- [ ] unique_key verified as truly unique\n- [ ] Row counts reasonable after incremental run\n- [ ] Late-arriving data handled (lookback window)\n- [ ] Schema changes handled (on_schema_change set)\n- [ ] Periodic full refresh scheduled\n","tagline":"Develops and troubleshoots dbt incremental models.
