As part of the schema synchronization procedure performed when starting, an SQL node now compares all databases on the cluster's data nodes with those in its own data dictionary, and if any of these is found to be missing from the SQL node's data dictionary, the SQL Node installs it loc...
To ensure that database objects in SQL scripts are resolved more precisely, we’ve implemented two resolve modes:PlaygroundandScript. The first one is the better option if your file is just a set of unconnected queries that are independent of each other and have no particular sequence. The se...
An epoch consists of multiple iterations, ensuring the entire dataset is used for training. Understanding these fundamental terms is essential for fine-tuning model performance and achieving accurate predictions. Let’s dive deep to learn what Epoch means in Machine Learning (ML), how it functions,...
