I have created a workflow which results into a table with approx. 150k of rows.
I want that this output table from the workflow to be populate a table already created in my amazon redshift data base.
The problem is that this what ever node i use to write/ insert data into the database table , it takes to long , like hours/days , this is not normal
is there a way to make this more fast?
the same output from Knime , is written in a few seconds in a excel file … just for comparison …
here is the end of my workflow ,
Do ypu guys have an idea what i can do or what node to use instead of the writer node ?
The DB Writer uses the DB’s SQL INSERT statements to write rows, which can be slow because after every insert the database updates indexes, statistics, etc. A faster was is to use the database’s bulk load functionality via the DB Loader node, which also supports Redshift. Please have a look at the workflow in this forum post for some inspiration. This should be much faster.
but due to the fact that i am still a beginner , i am not able to configure the following nodes:
What information are you missing to be able to configure the nodes? Have you looked at their node description? It explains pretty well what is required.
