ElasticSearch索引unix时间戳 [英] ElasticSearch index unix timestamp

问题描述

我必须索引包含'time'字段的文档，其值是一个整数，表示从历元（也称为unix时间戳）开始的秒数。

I have to index documents containing a 'time' field whose value is an integer representing the number of seconds since epoch (aka unix timestamp).

一直在阅读ES文档，并发现这一点：

I've been reading ES docs and have found this:

http://www.elasticsearch.org/guide/reference/mapping/date-format.html

但是，如果我想提交unix时间戳，并希望它们存储在date字段中（整数字段对我来说无用）我只有两个选项：

But it seems that if I want to submit unix timestamps and want them stored in a 'date' field (integer field is not useful for me) I have only two options:

• 实现自己的日期格式


• 在发件人转换为支持的格式

有没有其他选项我错过了？

Is there any other option I missed?

谢谢！

推荐答案

告诉ES字段的映射是一个日期，它可以使用时代毫秒作为输入。如果您希望ES自动检测，您将必须提供ISO8601或其他可发现的格式。

If you supply a mapping that tells ES the field is a date, it can use epoch millis as an input. If you want ES to auto-detect you'll have to provide ISO8601 or other discoverable format.

更新：我还应该注意，您可以影响ES将会识别哪些字符串作为映射中的日期。 http://www.elastic.co/guide/en/elasticsearch/ reference / current / mapping-date-format.html

Update: I should also note that you can influence what strings ES will recognize as dates in your mapping. http://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html
