Important
The SingleStore 9.1 release candidate (RC) is available now. It will be promoted to general availability (GA) soon and at that time it will be renamed to SingleStore 10.
In the interim, SingleStore 9.1 RC can be used to preview, evaluate, and provide feedback on the new and upcoming features in SingleStore 10, while SingleStore 9.0 is recommended for production workloads.

Examples
CREATE ROWSTORE TABLE neighborhoods (id INT UNSIGNED NOT NULL PRIMARY KEY,name VARCHAR(64) NOT NULL,population INT UNSIGNED NOT NULL,shape GEOGRAPHY NOT NULL,centroid GEOGRAPHYPOINT NOT NULL,index (shape) WITH (resolution = 8),index (centroid));INSERT INTO neighborhoods VALUES(1, "Hamilton", 12346, "POLYGON((1 1,2 1,2 2, 1 2, 1 1))","POINT(1.5 1.5)"),(2, "Probability Bay", 263951, "POLYGON((5 1,6 1,6 2,5 2,5 1))", "POINT(5.5 1.5)"),(3, "Decentralized Park", 29265, "POLYGON((5 5,6 5,6 6,5 6,5 5))", "POINT(5.5 5.5)"),(4, "Axiom Township", 845696, "POLYGON((1 5,2 5,2 6,1 6,1 5))", "POINT(1.5 5.5)"),(5, "Elegant Island ", 987654, "POLYGON((3 3,4 3,4 4,3 4,3 3))", "POINT(3.5 3.5)");
