How does a columnar database handle updates or inserts differently than a traditional RDBMS?

  • Columnar databases do not support updates or inserts.
  • Columnar databases store new data in separate tables.
  • Columnar databases use a write-optimized approach for inserts and updates.
  • Columnar databases use row-level updates like RDBMS.
Columnar databases handle updates and inserts differently by using a write-optimized approach. Instead of modifying existing data in place, they create new columnar segments to store incoming data, which is more efficient for analytical workloads but requires additional management.
