With the growing DRAM capacity and core count in modern servers, database systems are becoming increasingly multi-engine to feature a heterogeneous set of engines. ...
In particular, a memory-optimized engine and a conventional storage-centric engine may coexist for various application needs. ...
DESIGN PRINCIPLES We distill a set of desired properties and design principles that a cross-engine mechanism like Skeena should follow: • Low Overhead. ...
