Which Node is better than Database Reader for data loading performance?
If you need to read your data from a database, you can speed things up by already doing your preprocessing within the DB. See here for an example: https://www.knime.com/nodeguide/data-access/databases/database-advanced-example
I do believe that the KNIME Database table reader node or database writer node is not developed well as it is very poor performance compare with other products.
I see that so many users are complained about performance.. I don't know why they don't improve it,,
if they do not know how to fix it then they can look at other product how they developed as reference rather keep doing like this for years
referece product is Alteryx and it is very fast
