Different TTL Configuration for Parent/Child

TeeTim · March 7, 2013, 3:52am

For a single index with parent and child document mappings, does ES support
different TTL settings (enabled), via the Put Mapping API? In other words,
can a parent document have a different TTL setting than it's child
document? Or can only the parent document be configured with the TTL
setting?

Thanks in advance.

Hello Tim,

Yes, you can put different TTLs, as parents and children are different
documents with different mappings. You can test that with something like:

gist.github.com

https://gist.github.com/radu-gheorghe/5117021

parent_child_ttl.sh

curl -XDELETE localhost:9200/test
curl -XPUT localhost:9200/test
curl -XPUT localhost:9200/test/p/_mapping -d '{
    "p" :{
        "_ttl" : { "enabled" : true, "default": "10s" }
    }
}'
curl -XPUT localhost:9200/test/c/_mapping -d '{
    "c" :{
        "_ttl" : { "enabled" : true, "default": "20s" }

This file has been truncated. show original

But for that to work, you need to set indices.ttl.interval to something
like "1s" in your configuration and restart ES. Otherwise, _ttl will be
applied every 60s which will invalidate the test
