Trino Overview. Description Encryption is more efficient to be done as part of the page serialization process. Author (s): Matt Fuller, Manfred Moser, Martin Traverso. Configuring Trino. By default Trino does not implement fault tolerance for queries whose result set exceeds 32MB in size, such as SELECT statements that return a very large data set to the user. Tuning Presto. On the contrary, Trino is a query engine that can query data from object storage, relational database management systems (RDBMSs), NoSQL databases, and other systems, as shown in Figure 1-3. Configures how long the cluster runs without contact from the client application, such as the CLI, before it abandons and cancels its work. client. 9. No branches or pull requests. Trino was initially designed to query data from HDFS.
