Vector Bit Pattern Search
Hi,
I am trying to write a sample code where I could write the values into Buffer probable read the value from CSV file and store them in-memory and later do bit-pattern search, I am doing performance benchmark as my own study.
It would help me if someone could get me the sample code where I could do the search for the value String (with value vector).
Thanks,Sanjay

You can look at the complex writer to generate columns from csv rows:
