After you’ve reviewed and resolved any issues with the load, it’s a good idea to monitor/clean up the files that are generated in this directory so that they don’t waste your available storage.
Example:
dbadmin=> SELECT catalog_path FROM nodes;
catalog_path
----------------------------------------------------------
/home/dbadmin/test_db/v_test_db_node0001_catalog/Catalog
(1 row)
dbadmin=> CREATE TABLE test (c1 INT);
CREATE TABLE
dbadmin=> \! ls -lrt /home/dbadmin/test_db/v_test_db_node0001_catalog/CopyErrorLogs
total 0
dbadmin=> \! cat /home/dbadmin/test.txt

dbadmin=> COPY test FROM '/home/dbadmin/test.txt';

James Knicely
Vertica Field Chief Technologist
I've had the privilege of working with many database technologies in my career. But after being introduced to Vertica in May of 2011 as a client, I was hooked on the new technology after witnessing a query run in milliseconds that had previously ran for hours on the legacy database we had in place. It was then that I knew I wanted to eventually join the Vertica team, and 4 years later I did! I am currently a Vertica evangelist and am ready to help you get on board! Please feel free to reach out to me with any questions you have about Vertica and make sure to follow my Vertica Quick Tips!
