I've been working with ES 2.6 and the index like this one:

var response = MyElasticClient.Index(myObject,  
i =\> i.Type("mytype").Ttl(new Time(TimeSpan.FromDays(31))));

now stop working and the error goes like follow:

parse\_exception Reason: "failed to parse setting [ttl] with value [4.43w] as a time value: unit is missing or unrecognized"

How to set the TTL for the object?

Best regards  
Czaban

TTL functionality was deprecated in Elasticsearch 2.x and [removed in Elasticsearch 5.x](https://www.elastic.co/guide/en/elasticsearch/reference/5.6/breaking_50_mapping_changes.html#_literal __timestamp_literal_and_literal__ ttl_literal).

It was fundamental to us - is there any other mechanism that determines that an object is to be removed after a certain time?
