如何在不重新索引數據的情況下更新 ElasticSearch Mapping？

Question

我使用 elasticsearch 2.2.0 並創建如下數據映射：

{
"DOCU": {
    "_source": { "excludes" : ["fileAttachment.fileContent", "fileAttachmentFr.fileContent", "fileAttachmentEn.fileContent", "contentBody", "contentBodyFr", "contentBodyEn", "geoLocations.boundaries"] },

如何從映射中刪除排除字段（如下所示）：

"_source": { "excludes" : ["fileAttachment.fileContent", "fileAttachmentFr.fileContent", "fileAttachmentEn.fileContent", "contentBody", "contentBodyFr", "contentBodyEn", "geoLocations.boundaries"] }

我不想重新索引我的數據，因為它需要一整天才能完成。 請幫忙 ：）

Answer 1

在不重新索引的情況下無法更改 ElasticSearch 映射。

但是，您可以查看https://www.elastic.co/blog/changed-mapping-with-zero-downtime

這顯示了如何在幾乎零停機的情況下重新索引
