--------------------------------
Summary: [C++] JSON kernels
Key: ARROW-17268
URL: https://issues.apache.org/jira/browse/ARROW-17268
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: David Li
As discussed on dev@:
https://lists.apache.org/thread/onzgogx2c2djxs0wbhmvqp2dbx7kjf6o "[ARROW-17255]
Logical JSON type in Arrow"
It would be interesting to have JSON parsing/serializing compute functions that
operate on columns of (stringified) JSON records. For parsing, the problem is
we need to know the output schema without being able to look at the data, so we
would probably only be able to decode into a {{map[string, union]}} type at
best. And/or we could offer "extraction" functions akin to what things like
SQLite and Postgres provide (at the cost of having to reparse the JSON over and
over).
Also see ARROW-17255 for a logical JSON type.
