Can multidimensional hash values ββbe added to InfluxDB?
In InfluxDB, can you send multidimensional hash values ββto the database?
For example, this hash:
{
"field1": "value1",
"field2": {
"field2a": "value2a",
"field3a": "value3a"
}
}
If you can, how do you do it? When I try through the http admin interface, it makes no error or returns success.

Multidimensional values ββare not supported by InfluxDB. Points have fields that are a collection of key-value pairs. Currently, values ββcan only be float, integer, boolean, or string. InfluxDB has no concept of nested key values. The relevant source is here .
A workaround would be to store the JSON as a string literal by escaping all double quote characters (for example \"
). Then perform whatever functionality is required in the client.
curl -h -XPOST 'http://localhost:8086/write' -d '
{
"database": "test",
"retentionPolicy": "default",
"points": [
{
"name": "json_blob",
"tags": {
"tag1": "tag-value-a",
"tag2": "tag-value-b"
},
"fields": {
"value": "{\"field1\":\"value1\",\"field2\":{\"field2a\":\"value2a\",\"field3a\":"value3a\"}}"
}
}
]
}'
