Hi @Macarena, welcome to the community!

May I ask if you’ve tried the troubleshooting steps?

Amazon Redshift driver has buffer size set to 2 GB by default. Results of Redshift queries are buffered into ONE Desktop process memory, which has reserved size of 1 GB. In order to prevent possible memory issues with data intensive queries we recommend decreasing the size of the buffer by adding the following parameter to your Redshift connection string:

fetchRingBufferSize=1M sets the ring buffer size to 1 MB, which should be sufficient for most usability scenarios.

Example of a Redshift connection string:  jdbc:redshift://redshiftdb.com:5439/dev;fetchRingBufferSize=1M
