How can partitioning be used in migration strategies for large databases?

  • Applying horizontal sharding
  • Employing vertical scaling
  • Leveraging data mirroring
  • Utilizing partition switching
Partitioning is a technique where a large table is divided into smaller, manageable parts. In database migration, partitioning allows migrating data in smaller, more manageable chunks, reducing downtime and enabling parallel processing. Partition switching is a method where a partition of a table is moved in or out of a table quickly, useful for large-scale data movements without impacting other parts of the system.
