Hi,
When I use PROC COPY with INDEX=YES, MEMTYPE=ALL & CONSTRAINTS=YES options I'm getting below INFO message in SAS Log
INFO: Engine's block-read method cannot be used because:
INFO: - The file is compressed
I read somewhere that using block-read increases the performance, as I need to use copy on many libraries/datasets I have a question.
Is there any way where we can force SAS to use block-read even when file is compressed?
