>             Project: Calcite
>          Issue Type: Bug
>          Components: avatica

> When sending a typed value as a byte string to avatica using protocol buffers, it does not accept the bytes as an array of raw bytes in the {{bytes_values}} field.
> To work around it, the data needs to be first base64 encoded and then sent in the {{string_value}} field.
> This is the decoded protocol buffer being sent by the thin client:
> {code}
> 1: "org.apache.calcite.avatica.proto.Requests$ExecuteRequest"
> 2 {
>   1 {
>     1: "5141356e-f331-48c9-9d01-d71176ad92e8"
>     2: 126
>     3 {
>       2: "UPSERT INTO PQS.INTEGER_TABLE VALUES(?, ?)"
>       3 {
>         4: 4
>         5: "INTEGER"
>         6: "java.lang.Integer"
>         7: "?1"
>       }
>       3 {
>         4: 4294967293
>         5: "VARBINARY"
>         6: "[B"
>         7: "?2"
>       }
>       4 {

>       }
>     }
>   }
>   2 {
>     1: 12
>     4: 2
>   }
>   2 {
>     1: 20
>     // Data sent in string_value and base64 encoded
>     3: "iVBORw0KGgoAAAANSUhEUgAABmIAAAiwCAYAAAAvCT8OAAAACXBI..."
>   }
