Db2: High Availability and OLTP Powerhouse

  • By Astra S.
  • on 03/07/2025

What do you like best about the product?
IBM Db2 is excellent for high availability and disaster recovery strategies particularly with HADR and Q replication for near real-time failover. The row-level locking mechanism optimizes OLTP workloads, ensuring efficient concurrency control without excessive blocking.
What do you dislike about the product?
Db2’s cloud-native integration lags behind modern cloud-first databases like Aurora or Spanner. Although IBM provides Db2 on Cloud, its Kubernetes operator lacks the automation maturity seen in competitors like CockroachDB or YugabyteDB.
What problems is the product solving and how is that benefiting you?
The native columnar storage for analytical workloads allows for hybrid OLTP and OLAP processing, reducing the need for separate analytics databases.
