> I have a strange error using Apache Druid avatica protobuf endpoint. I send
> this query:
> SELECT "user",
> cast("added" as float) m3
> from "wikipedia"
> limit 10
>
> and I get this without a stacktrace:
> ClassCastException: class java.lang.Long cannot be cast to class
> java.lang.Float (java.lang.Long and java.lang.Float are in module java.base
> of loader 'bootstrap')
>
> I works with `double` though:
> SELECT
> cast(1.0 as double) m3
> from "wikipedia"
>
> The screenshot shows the exception is thrown here:
> !image-2023-10-23-13-45-59-828.png!
