Baidu In-Memory Databases Add Intel Optane

Chinese e-commerce giant Baidu is building a new platform based on Intel Corp.’s Optane DC persistent memory as a means of upgrading search engine results delivered by its in-memory databases used to feed its streaming data services.

The partners also published a case study this week detailing the restructuring of its in-memory database using Optane memory technology introduced last year. Baidu said it plans to shift its in-memory databases to an Optane-only configuration as a replacement for DRAMs.

Baidu said combination of Optane and Intel’s second-generation Xeon Scalable processor allowed the core module of its Feed Stream recommendation engine to boost memory density per device. The result was reduced cost in running a Redis in-memory database as well as a Spark distributed in-memory computing engine.

As the movement of data between cloud storage and DRAM becomes a bottleneck, Baidu said it plans to incorporate Optane into its Spark-based platform to boost device memory density.
