Before the widespread adoption of HTAP, enterprises had to go through complex ETL (Extract, Transform, Load) processes to move business data from production databases to analytics databases. This model had two fatal flaws:
  • Low data freshness: Analysts often see "old accounts" from hours or even a day ago.
  • Bloated architecture: It requires maintaining two independent systems and hardware, resulting in extremely high operation and maintenance costs.


The Breakthrough Path of HTAP: One Data Source, Two Formats
Modern HTAP databases, such as TiDB and OceanBase , have solved this problem through innovative **Hybrid Row/Columnar** technology:
1. Strongly consistent row store
For routine business processes such as order placement, payment, and fund transfer, the database uses row-based storage . It utilizes consensus protocols such as Raft or Paxos to ensure transaction consistency under high concurrency, guaranteeing that every transaction is accurate and error-free.
2. Automatically synchronized columnar store
Meanwhile, databases automatically convert data into column-oriented storage replicas via asynchronous or real-time mechanisms (such as TiDB's Raft Learner nodes) . The latest database column-oriented storage is an "accelerator" for complex analysis; it reads only the columns relevant to the query, increasing the speed of aggregation and analysis of massive amounts of data by hundreds of times.
3. Intelligent routing and resource isolation
When a user initiates a query, HTAP's intelligent optimizer automatically makes decisions: simple single-record queries are sent to the "row storage"; complex annual trend reports are routed to the "column storage." The isolation of physical resources ensures that even when running massive amounts of reports, the front-end business will not experience any lag.

Typical application scenarios in 2026
  • Real-time risk control: While processing card transactions (TP), financial institutions instantly run risk models (AP) to intercept illegal transactions within milliseconds.
  • Real-time marketing: E-commerce platforms adjust promotional prices instantly based on real-time sales data and user behavior (HTAP real-time feedback) to achieve precise conversion.


In summary, HTAP enables "what you see is what you get" data analysis. It not only simplifies IT architecture but also transforms data from a lagging "historical record" into "real-time navigation" that drives business.
Do you want to understand how to introduce TiDB or OceanBase into your existing business, or do you want an in-depth comparison of the performance differences between these two domestic databases in their latest 2026 versions?
