我'獲取數據上Couchbase和工作Elasticsearch與春天數據。我有一個從Couchbase到Elasticsearch的複製。現在我可以使用spring數據將數據保存在couchbase中,數據被正確保存並被複制到Elasticsearch中。在嘗試從Elasticsearch讀取時,它顯示爲空,只有結果中顯示id值。當我直接保存在Elasticsearch中時,可以正確讀取。我想這是因爲數據的結構變化。我該如何解決這個問題?無法從Elasticsearch
數據在Elasticsearch複製後:
{
"_index": "streams",
"_type": "couchbaseDocument",
"_id": "e8c7999c-67c8-47a4-b235-726d89102f83",
"_score": 1,
"_source": {
"meta": {
"id": "e8c7999c-67c8-47a4-b235-726d89102f83",
"rev": "3-000007c43e1293830000000000000000",
"expiration": 0,
"flags": 0
},
"doc": {
"createdOn": "20141201183646786",
"activityId": "c3c0dc11-16b5-479b-80c5-93d2ce34d77d",
"_class": "com.netspective.streams.model.Activity",
"documentType": "Activity",
"objectId": "UserAgent_1",
"subjectId": "{"actionId":"111"}",
"actionId": "2",
"updatedOn": "20141201183646786",
"deleteStatus": false
}
}
}
數據在Elasticsearch是直接插入:
{
"_index": "streams",
"_type": "couchbaseDocument",
"_id": "45ebb326-a33e-43f2-9fd7-60953cb14772",
"_score": 1,
"_source": {
"id": "45ebb326-a33e-43f2-9fd7-60953cb14772",
"activityId": "56d291bc-eacd-4942-b26d-08025eec0ab1",
"subjectId": "{"actionId":"123"}",
"objectId": "UserAgent_1",
"documentType": "Activity",
"createdOn": "20141202113523979",
"updatedOn": "20141202113523979",
"deleteStstus": false,
"action": "2"
}
}
是否可以刪除文檔和元字段?在模板中,它只允許告訴需要複製的字段,我認爲它不允許更改結構。是嗎? – 2014-12-03 05:04:12
