[SDK] Support to transform from PB protocol to CSV/KV protocol by single SQL
Fixes #10117
Parent issue:
#10022
### Motivation
Support to transform from PB protocol to CSV/KV protocol by single SQL
### Modifications
- Support to parse the following PB protocol
`
syntax = "proto3";
package test;
message SdkMessage {
bytes msg = 1;
int64 msgTime = 2;
map<string, string> extinfo = 3;
}
message SdkDataRequest {
string sid = 1;
repeated SdkMessage msgs = 2;
uint64 packageID = 3;
}
`
- Support to parse the following PB data
`
SdkDataRequest.Builder requestBuilder = SdkDataRequest.newBuilder();
requestBuilder.setSid("sid");
requestBuilder.setPackageID(1);
{
SdkMessage.Builder msgBuilder = SdkMessage.newBuilder();
msgBuilder.setMsgTime(1713243918000L);
msgBuilder.setMsg(ByteString.copyFrom("msgValue4".getBytes()));
msgBuilder.putExtinfo("key", "value");
SdkMessage msgObj = msgBuilder.build();
requestBuilder.addMsgs(msgObj);
}
{
SdkMessage.Builder msgBuilder = SdkMessage.newBuilder();
msgBuilder.setMsgTime(1713243918002L);
msgBuilder.setMsg(ByteString.copyFrom("msgValue42".getBytes()));
msgBuilder.putExtinfo("key2", "value2");
SdkMessage msgObj = msgBuilder.build();
requestBuilder.addMsgs(msgObj);
}
SdkDataRequest requestObj = requestBuilder.build();
`
- Generate the final data by the following SQL
select $root.sid,
$root.packageID,
$child.msgTime,
$child.msg from source
- The final data is the following string
value1|value2|1713243918000|value4
value1|value2|1713243918000|v4
