- 我在 mongoDB 中有很多文档。Mongo-connector 将这些数据插入到 elasticsearch。有没有办法,在插入到 ES 之前,我们可以在文档中添加额外的字段,然后插入到 elasticsearch 中?mongo-connector 有什么办法可以做到以上几点吗?
更新
根据您的更新 3 ,我创建了类似这样的映射,对吗?
PUT my_index2
{
"mappings":{
"my_type2": {
"transform": {
"script": {
"inline": "if (ctx._source.geopoint.alt) ctx._source.geopoint.remove('alt')",
"lang": "groovy"
}
},
"properties": {
"geopoint": {
"type": "geo_point"
}
}
}
}
}
错误
这是我尝试插入映射时不断遇到的错误
{
"error": {
"root_cause": [
{
"type": "script_parse_exception",
"reason": "Value must be of type String: [script]"
}
],
"type": "mapper_parsing_exception",
"reason": "Failed to parse mapping [my_type2]: Value must be of type String: [script]",
"caused_by": {
"type": "script_parse_exception",
"reason": "Value must be of type String: [script]"
}
},
"status": 400
}

现在映射被插入并得到确认为真。但是,当尝试插入 json 数据时,如下面的抛出错误。
PUT my_index2/my_type2/1
{
"geopoint": {
"lon": 48.845877,
"lat": 8.821861,
"alt": 0.0
}
}
UPDATE2 错误
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "failed to parse"
}

添加 script.inline:true 后,尝试插入数据但出现以下错误。
{
"error": {
"root_cause": [
{
"type": "parse_exception",
"reason": "field must be either [lat], [lon] or [geohash]"
}
],
"type": "mapper_parsing_exception",
