Vertical Scaling in OceanBase: Upgrade Node Capacity Without Database Downtime
This is the third article in OceanBase's Elastic Scaling series, covering vertical scaling — replacing existing nodes with higher-spec machines while keeping the cluster's logical topology (node count) unchanged, making the process nearly transparent to applications.
Scale Out Without Downtime: How OceanBase Adds Nodes Online
Learn how OceanBase achieves zero-downtime horizontal scaling through automatic data rebalancing, Multi-Paxos consensus, and transparent routing via ODP. Add nodes with a single parameter change.
OceanBase Tenant-Level Scaling: Adjust Resources in Seconds
OceanBase tenant-level scaling adjusts CPU, memory, and IOPS quotas in seconds — no data migration, no failover, no application changes. Here's how it works.
How to Eliminate Manual Database Sharding and Scale Writes Without Application Complexity
Learn how OceanBase eliminates manual sharding with transparent partitioning, automatic routing, distributed transactions, and online rebalancing.
Zero Data Loss, Fast Failover: How OceanBase Uses Multi-Paxos for High Availability
How OceanBase uses Multi-Paxos, log streams, replica types, and leader election to achieve zero data loss and fast failover.
