With this commit we change the data type of the 'TIMESTAMP' meta-data field from a formatted date string to a plain `java.util.Date` instance. The main reason for this change is that our benchmarks have indicated that this contributes significantly to the time spent in the ingest pipeline. The overhead in terms of indexing throughput of the ingest pipeline is about 15% and breaks down roughly as follows: * 5% overhead caused by the conversion from `XContent` -> `Map` * 5% overhead caused by the timestamp formatting * 5% overhead caused by the conversion `Map` -> `XContent` Relates #22074

== Breaking changes in 6.0
|
|
|
|
This section discusses the changes that you need to be aware of when migrating
|
|
your application to Elasticsearch 6.0.

|
=== Indices created before 6.0
|
|
|
|
Elasticsearch 6.0 can read indices created in version 5.0 or above. An
|
|
Elasticsearch 6.0 node will not start in the presence of indices created in a
|
|
version of Elasticsearch before 5.0.
|
|
|
|
[IMPORTANT]
|
|
.Reindex indices from Elasticseach 2.x or before
|
|
=========================================
|
|
|
|
Indices created in Elasticsearch 2.x or before will need to be reindexed with
|
|
Elasticsearch 5.x in order to be readable by Elasticsearch 6.x. The easiest
|
|
way to reindex old indices is to use the `reindex` API.
|
