Asynchronous result support
Description
When a DSResult-class object is returned on aggregation or assignment operation,
the raw result can be accessed asynchronously, allowing parallelization of DataSHIELD calls
over multpile servers. The returned named list of logicals will specify if asynchronicity is supported for:
aggregation operation ('aggregate'), table assignment operation ('assignTable'),
resource assignment operation ('assignResource') and expression assignment operation ('assignExpr').
Usage
dsIsAsync(conn)
Arguments
