I have an application to read data from and I have two options either to use ODBC or OPC UA directly

What are the benchmarks or limitations when it comes to above

I have 30,000 data points to read with sample time of 1s and 5s and 10s

The OPC-UA extractor is specialized for reading large amounts of data points, more so than the DB extractor. That said, this is often mostly dependent on the source system. It is likely that the OPC-UA interface for this solution just reads from the underlying database, in which case it may be much less efficient.

I can only advise that you try OPC-UA, and switch to ODBC if it is too slow.
