 ## Introduction
 
-Linkis helps easily connect to various back-end computation/storage engines(Spark, Python, HBase ...), exposes various interfaces(REST, WebSocket, Java ...), with multi-tenancy, high performance, and resource control.
+Linkis helps easily connect to various back-end computation/storage engines(Spark, Python, TiDB...), exposes various interfaces(REST, JDBC, Java ...), with multi-tenancy, high performance, and resource control.
 
 Linkis connects with computation/storage engines(Spark, Hive, Python and HBase), exposes REST/WS interface, and executes multi-language jobs(SQL, Pyspark, HiveQL and Scala), as a data middleware.
 
-Based on the microservices architecture, Linkis provides enterprise-level features of financial-level multi-tenant isolation, resource management and access control. It also offers convenient support to manage unified variables, UDFs, functions and resource files. it is also guaranteed with sophisticated task/job lifecycle management capabilities under high-concurrency, high-performance and high-availability scenarios.
