This document discusses SkySQL and MariaDB database solutions. It provides an overview of the SkySQL architecture including MariaDB servers using MHA Galera clusters, a gateway, manager, and monitoring tools. It describes features of MariaDB like optimizations, group commit, atomic writes, virtual columns, TokuDB, and connectors. It also discusses high availability using Pacemaker for automatic failover, the SkySQL manager dashboard, REST API, and gateway for load balancing and query routing.

VIRTUAL COLUMNS
•For InnoDB, MyISAM andAria
•PERSISTENT (stored) or VIRTUAL
(generated)
CREATE TABLE t1 (
c1 INT NOT NULL,
c2 VARCHAR(32),
c3 INT AS
( c1 MOD 10 ) VIRTUAL,
c4 VARCHAR(5) AS
( LEFT(B,5) ) PERSISTENT);
DYNAMIC COLUMNS
•Implement a schemaless,
document store
•COLUMN_ CREATE,ADD, GET, LIST,
JSON, EXISTS, CHECK, DELETE
•Nested colums are allowed
•Main datatypes are allowed
•Max 1GB documents
CREATE TABLE assets (
item_name VARCHAR(32) PRIMARY KEY,
