pg_later
Execute SQL now and get the results later.
A postgres extension to execute queries asynchronously. Built on pgmq.
Installation
Run with docker
docker run -p 5432:5432 -e POSTGRES_PASSWORD=postgres quay.io/tembo/pglater-pg:latest
If you’d like to build from source, you can follow the instructions in CONTRIBUTING.md.
Using the extension
Initialize the extension’s backend:
CREATE EXTENSION pg_later CASCADE;
SELECT pglater.init();
Execute a SQL query now:
select pglater.exec(
'select * from pg_available_extensions order by name limit 2'
) as job_id;
job_id
--------
1
(1 row)
Come back at some later time, and retrieve the results by providing the job id:
select pglater.fetch_results(1);
