[FIXED] How to set a TTL for an index in ElasticSearch

Issue

I would like to know how can I set a TTL so that each document older than 30 days are automatically removed by the ES cluster.

I know previous versions used to manage this using the TTL field but it seems it is removed now.

I'm using NEST.NET 6.4.0

Solution

TTL was removed in 5.0

you can use curator , shedule it as cronjob or jenkins job , and delete old indices all together.

curator_cli --host  localhost --port 9200 --http_auth "$USER":"$PASS" \
delete_indices --ignore_empty_list --filter_list '[{"filtertype":"age","source":"creation_date","direction":"older","unit":"days","unit_count":30}, \
{"filtertype":"pattern","kind":"prefix","value":"livelogs"}]'
