Why ES remove TTL and how it is replaced?

[makeyang]

I guess there must be some issues cased by TTL, can anybody share them(like github issue links) to me?
and how it is replaced?

Hi,

This issue has some reasons: https://github.com/elastic/elasticsearch/issues/18280
This issue adds some documentation with suggestions how to migrate: https://github.com/elastic/elasticsearch/pull/19014

This is also part of the documentation about mapping changes in the upcoming 5.0 release: https://www.elastic.co/guide/en/elasticsearch/reference/5.0/breaking_50_mapping_changes.html
