overridevirtual

This method stores several payloads in batch mode on the file storage.

(This method is an analogue of the store_data method in Python)

Parameters

tag	- tag name.
storeSetJson	- iov and payload data as a JSON object.
payloadFormat	- payload format [FILE | JSON].
objectType	- object type.
compressionType	- compression type.
version	- version.
endTime	- end time, if endtime = 0, the server does not use this parameter in the internal check.

Example how to use these parameters:

   std::string tag = "test_MvG3a";
   uint64_t endtime = 200;
   std::string objectType = "test";
   std::string compressionType = "none";
   std::string version = "1.0";
   std::string payloadFormat = "JSON";
   std::string jsonString = R"({"size": 1, "datatype": "data", "format": "StoreSetDto", "resources": [{"since": 1000,"data": "Sample data","streamerInfo": "Info123"}]})";
   StoreSetDto storeSetJson = StoreSetDto::from_json(jsonString);

storePayloadDump()

private

This auxiliary method stores a single payload (with since time) on the file system.

Parameters

tag	- tag name.
since	- since parameter,
js	- a string with a payload or file (the path and the file name) with payload.
payloadFormat	- payload format [FILE | JSON].
objectType	- object type.
compressionType	- compression type.
version	- version.
endTime	- end time, if endtime = 0, the server does not use this parameter in the internal check.
