Which of the following options does not belong to the GaussDB database features?

Question

Options

• AHigh scalability, strong consistency of distribution, TPCC expansion ratio > 0.8
• BHigh availability, fault switching time < 10s, and support flashback
• CSupport stream processing features
• DHigh performance, based on the Kunpeng 920 processor, the performance of a single machine

• C
  95% (20)
• D
  5% (1)

Explanation

Option C is the correct answer because stream processing is not a native feature of GaussDB - that capability belongs to dedicated streaming engines like Apache Flink or Kafka Streams. GaussDB is a relational database optimized for OLTP/OLAP workloads, not real-time stream computation.

Why the distractors are wrong (i.e., they DO belong to GaussDB):

• A is a genuine GaussDB feature: it uses distributed architecture with strong consistency guarantees, and its TPCC scale-out ratio exceeding 0.8 is a documented benchmark claim.
• B is accurate: GaussDB targets high availability with sub-10-second failover and supports flashback queries for point-in-time data recovery.
• D is accurate: GaussDB's single-node performance is specifically optimized for Huawei's Kunpeng 920 ARM-based processor, which is a core part of its marketing.

Memory tip: Think of GaussDB as a storage and query database - it scales out, stays consistent, recovers fast, and runs fast on Kunpeng hardware. The moment you see "stream processing," that's a pipeline/event concern (Flink, Spark Streaming) - a different tool family entirely. If the answer involves real-time data flowing through, it's not GaussDB.
