> For large databases, standard initialization may take **SEVERAL HOURS** and require significant disk space (approx 2x table size).
There are two strategies for initialization:
**A. Standard Initialization (Default)**:
**A. Standard Initialization (`--init`)**:
Scans the database to find the oldest record (`MIN(clock)`) and creates partitions from that point forward.
