As a Kafka subscriber, I am getting 2000+ records within 10 seconds and storing in one collection one by one (100+ millions records).
For deletion, I have scheduler that runs every 30 minutes. I need to delete records older than 2 days. Because mongo id is indexed by default. I am using it as a condition to delete by converting datetime to mongo object id
(Node JS code)
time = new ObjectID(moment().subtract(2, ‘days’).valueOf()/1000);
Problem is, this delete query takes too much time to finish ( and increase CPU utilization). Is there any alternative way to delete old records? I heard about TTL but not sure if it works with large collection.
Thanks in advance.
