Competitive Analysis

...

Most industrial vendors rely on the following techniques:

• Favor sequential IO over random
• Maintenance of internal database data structures is expensive, it is better to rebuild them from scratch in bulks when data load is finished
• Acquiring of per-entry locks is expensive, so it is better to escalate lock to upper level (typically - table)
• Crash recovery of data being loaded is typically not needed
