Hi, As per the CEP guideline, I am sending this email to start a discussion about Storage-Attached-Index[1][2] for Apache Cassandra.
A team at DataStax has developed a new index implementation, called Storage Attached Index(SAI), based on the advancement made by SASI. SAI improves: * disk usage by sharing of common data between multiple column indexes on the same table and better compression of on-disk structures. * numeric range query performance with modified KDTree and collection type support. * compaction performance and stability for larger data set. There is a more detailed explanation about SAI design in the CEP document. To make the technical discussion simpler, we created a slack channel #cassandra-sai. We are looking forward to the community's feedback and suggestions.
