![]() ![]() Only one machine is used as a primary server in Tableau Server environment.ĥ. For multiple server configurations, one physical system works as a primary server, and others are used as worker servers. For single server configuration, one gateway or primary server manages all the processes. In case of absence of external load balancer, the gateway also works as a load balancer. ![]() The gateway works as a distributor of processes to different components. When the client sends a request, it is forwarded to the external load balancer for processing. Gateway: The gateway directed the requests from users to Tableau components. The data source can extract the data as well as make live connections with external data sources.Ĥ. It stores the related details of data set like calculated fields, metadata, groups, sets, and parameters. It provides data security, metadata management, data connection, driver requirements, and data storage. Data server: Data server is used to store and manage the data from external data sources. The cache can be shared between many users who have permission to view the visualization.Ĭ. Tableau server creates a cache of visualization to reduce the load time. This visualization or image is presented for the users. Once the client request is forwarded to the VizQL process, it sends the query directly to the data source retrieves information in the form of images. VizQL server: VizQL server is used to convert the queries from the data source into visualizations. The administrator is configuring the default timeout of the session in the server.ī. It gives a guarantee of security by recording each session id on Tableau Server. It handles the permission and administration for mobile and web interfaces. Application server: The application server is used to provide the authorizations and authentications. Components of Tableau server: Different types of component of the Tableau server are:Ī. Extracted data allows the users to visualize the data offline, without connecting to the data source.ģ. This improves performance, especially when we are working on massive datasets. Using filters, Tableau can extract a few records from a large dataset. Tableau's data engine uses storage such as ROM, RAM, and cache memory to process and store data. It can remove millions of records in the Tableau data engine with a single click. We make a local copy in the form of Tableau extract file. Extracted or in-memory data: Tableau is an option to extract the data from external data sources.In these cases, Tableau works as a front-end visualization tool by connecting with the live data. Mostly in other enterprises, the size of the database is large, and it is updated periodically. It makes optimized and a fast database system. This feature can be used as a linking between the live data and Tableau rather than importing the data. It uses the infrastructure existing database by sending dynamic multidimensional expressions (MDX) and SQL statements. Real-time data or live connection: Tableau can be connected with real data by linking to the external database directly.On the uses basis, one can be easily switched between live and extracted data. Tableau desktop has an option to select both extract and live data. This ODBC Connector can be connected with any databases without using their native connector. Data connector:- The Data Connectors provide an interface to connect external data sources with the Tableau Data Server. It can also make the relationship between different types of data sources.Ģ. It can connect to an excel file, database, and a web application at the same time. It can blend the data from various data sources. Tableau can connect with multiple data sources. Data server:- The primary component of Tableau Architecture is the Data sources which can connect to it. Let's study about the different component of the Tableau architecture:ġ. The different layers used in Tableau server are given in the following architecture diagram:. Providing such powerful features requires unique architecture. It is a multi-process, multi-user, and multi-threaded system. It can run on both the physical machines and virtual machines. ![]() Tableau Desktop is a powerful data visualization tool. It can connect clients from Mobile, Web, and Desktop. Tableau Server is designed to connect many data tiers. ![]()
