After reading the documentation on TTL, it seems as though the following is not supported: Enable TLL processing but by default all documents live forever, and only specific documents are indexed with "\_ttl":"_time_" so that they are expired after the _time_ has passed. Or is this an all-or-nothing proposition in which all documents are given a TLL (even if a default). In other words, if any documents are immortal, then all must be immortal? And if at least one is to be made mortal, then all are mortal? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
