Kyligence Connector

Founded by the creators of Apache Kylin, Kyligence is on a mission to accelerate the productivity of its customers by automating data management, discovery, interaction and insight generation – all without barriers. Kyligence enables Tableau customers to scale their data with unmatched performance and seamless integration.

Tableau users can analyse petabytes of data on the big data platform with sub-second query latency, and can conduct multi-dimensional and ad-hoc queries using a live connection between Kyligence and Tableau.

Kyligence automatically syncs models with Tableau to avoid duplicated effort and human error and connects data sources on Hadoop platform and accelerates queries.
