datasnap

I have a JSON Object, let's name it jObject that looks like this: { "id": 0, "data": "[{DAT_INCL: \"08/03/2012 10:07:08\", NUM_ORDE: 1, NUM_ATND: 1, NUM_ACAO: 2, NUM_RESU: 3}, {DAT_INCL: \"08/03/2012 10:07:09\", NUM_ORDE: 2, NUM_ATND: 1, NUM_ACAO: 4, NUM_RESU: 5}, {DAT_INCL: \"08/03/2012 10:07:09\", NUM_ORDE: 3, NUM_ATND: 1, NUM_ACAO: 8, NUM_RESU: NULL}]" } As you can see, it contains two pairs, one of which is an array with three objects in this case (the amount of objects is dynamic) with multiple "key: values"(these don't vary, being always the same 5 fields), which I want to insert into an

We use stateful DataSnap servers for some business logic tasks and also to provide clientdataset data. If we have to update the server to modify a business rule, we copy the new version into a new empty folder and register it (depending on the Delphi version, just by launching or by running the TRegSvr utility). We can do this even while the old server instance is running. However, after registering the new version, all new client connections will still use the currently running (old) server instance . All clients have to disconnect first, then the new server will be used for the next clients.

I have a Delphi 10.1 Berlin Datasnap Server, that can't return Data packets (through a TStream) bigger than around 260.000 bytes. I have programmed it following the \Object Pascal\DataSnap\FireDAC sample from Delphi, which also shows this problem. The problem can be seen just opening that sample, setting blank the IndexFieldName of the qOrders component on ServerMethodsUnit.pas, and changing its SQL property to : select * from Orders union select * from Orders Now the amount of data to be send is beyond 260.000 bytes, which seems to be the point where you can't retrieve it from the client.
