-## Batch INSERT Statements for Bulk Data
-
-Individual INSERT statements have high overhead. Batch multiple rows in single statements or use COPY.
-
-**Incorrect (individual inserts):**
-
-```sql
--- Each insert is a separate transaction and round trip
-insert into events (user_id, action) values (1, 'click');
-insert into events (user_id, action) values (1, 'view');
-insert into events (user_id, action) values (2, 'click');
--- ... 1000 more individual inserts
-
--- 1000 inserts = 1000 round trips = slow
-```
-
-**Correct (batch insert):**
-
-```sql
--- Multiple rows in single statement
-insert into events (user_id, action) values
-  (1, 'click'),
-  (1, 'view'),
-  (2, 'click'),
-  -- ... up to ~1000 rows per batch
-  (999, 'view');
-
--- One round trip for 1000 rows
-```
-
-For large imports, use COPY:
-
-```sql
--- COPY is fastest for bulk loading
-copy events (user_id, action, created_at)
-from '/path/to/data.csv'
-with (format csv, header true);
-
--- Or from stdin in application
-copy events (user_id, action) from stdin with (format csv);
-1,click
-1,view
-2,click
