Hello,
I've upgraded my cluster from 6.8.0 to 7.8.0. This is my template:
{
"index_patterns": [
"example-*"
],
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0,
"refresh_interval": "20s",
}
"mappings": {
"dynamic": false,
"properties": {
"@timestamp": {
"type": "date"
}
}
}
}
When I save my document this is what I get:
"_index": "example-000001",
"_type": "_doc",
"_id": "gV2ZAHMBqN3Ho-B9PIfj",
"_version": 1,
"_score": null,
"_source": {
"@timestamp": "2020-06-29T15:01:49.000Z"
},
"fields": {
"@timestamp": [
"2020-06-29T15:01:49.000Z"
]
},
"sort": [
1593442909000
]
}
What is this new fields
key I see on my documents? I hadn't it on my old elasticsearch 6.8.0.
I did some testing and I've found that every field I define in my template using date
ends up inside fields
key on the document
