I have a key field on the time field which I have defined as a bigint since the time I get from InfluxDB is an epoch time. My question is does psql abort the copy if it hits a duplicate key, or does it keep processing? The copy will fail. You could import into a temporary table and preprocess then copy to your permanent table or use an ETL solution to remove unwanted data before importing. I don't know the nature of your data or project but perhaps that column isn't suitable for a key. Cheers, SteveI am attempting to periodically pull time series data from an InfluxDB. The column at issue is the timestamp. I have a script that pulls the last 15 minutes of data from the InfluxDB as csv data and pipe it into a psql -c "\copy...." command. I was looking for the simplest way to do this.Then as suggested above pull into staging table that has no constraints e.g. PK. Verify data and then push into permanent table. -- Stephen Clark *NetWolves Managed Services, LLC.* Sr. Applications Architect Phone: 813-579-3200 Fax: 813-882-0209 Email: steve.clark@xxxxxxxxxxxxx http://www.netwolves.com --
