--------------------------------
Summary: ElasticSearchSink ttl field modification to mimic
Elasticsearch way of specifying TTL
Key: FLUME-2206
URL: https://issues.apache.org/jira/browse/FLUME-2206
Project: Flume
Issue Type: Improvement
Components: Sinks+Sources
Affects Versions: v1.5.0
Reporter: Dib Ghosh
Priority: Minor
According to current ElasticSearch documentation of TTL:
"In case you do not specify a time unit like d (days), m (minutes), h (hours),
ms (milliseconds) or w (weeks), milliseconds is used as default unit.
If no default is set and no _ttl value is given then the document has an
infinite _ttl and will not expire."
Current flume ElasticSearchSink index TTL configuration:
agent.sinks.myESsink.ttl = <some integer value> and defaults to 5 days.
It will be good to have a qualifier like "d" / "s" / "m" / "w" / "h" to mimic
the TTL configuration in ElasticSearch mapping.
When user specifies agent.sinks.myESsink.ttl = "3w" index TTL should be set to
3 weeks while agent.sinks.myESsink.ttl = 3 will set the TTL to 3 days.
