Pls see CALCITE-3560 [1] which was merged recently. You can now instantiate
Source from a generic CharSource [2]:
Source source = Sources.fromCharSource(CharSource.wrap("hello"));
This should be released with 1.22

Hi guys ,
i have another question about this adapter.
I have a json sample like this :
[
{
"field": "test",
"properties": [
"a",
"b",
"c"
]
}
]
JsonTable look like to convert Array to OTHER ColumType .
the column "properties" is converted on '
when i check
Big Thank Guys !!!
Even if this CSVAdapter is an "example" its still really usefull :) and
with this update it will be a good "out of box" tools usable in many
scenario/workflow

I'm not planning to change Source.java it already exposes Reader /

I see that this feature request relates to Source.java and Sources.java, which
are in org.apache.calcite.util in core.
If you add some capability, it is fine to add It to the CSV adapter example,
but it is much more important that that capability exists in the file adapter.

I think the change is straightforward (will not add complexity).

Remember that CsvAdapter is in the “example” module. Keep it simple.
The file adapter can also parse CSV files.

Hello,
Source object already exposes Reader / InputStream API. Probably
JsonEnumerator can be changed to use those methods.
Do you mind creating a JIRA ticket ? I'll take a look.
Thanks,
Andrei.

Hi guys ,
I saw in the code that this nice adapter makes it possible to make SQL
queries on the data JSON
https://github.com/apache/calcite/tree/ab71c4cae5a5c3c7d979337a2d38ddaf271aa206/example/csv/src/main/java/org/apache/calcite/adapter/csv
But it's limited on File / URL.
JsonTable constructor
