All JSON-supported types will be parsed (null, boolean, number, array, object, string).
Suppose you provide this configuration of the json
processor:
{ "json" : { "field" : "string_source", "target_field" : "json_target" } }
If the following document is processed:
{ "string_source": "{\"foo\": 2000}" }
after the json
processor operates on it, it will look like:
{ "string_source": "{\"foo\": 2000}", "json_target": { "foo": 2000 } }
If the following configuration is provided, omitting the optional target_field
setting:
{ "json" : { "field" : "source_and_target" } }
then after the json
processor operates on this document:
{ "source_and_target": "{\"foo\": 2000}" }
it will look like:
{ "source_and_target": { "foo": 2000 } }
This illustrates that, unless it is explicitly named in the processor configuration, the target_field
is the same field provided in the required field
configuration.
