QUESTION
I have a code
column which I would like to pass to a web service and update two fields in the dataframe (dfMRD1['Cache_Ticker']
and dfMRD1['Cache_Product']
with two values from the returned JSON (RbcSecurityDescription
and RbcSecurityType1
). I have achieved this by iteration but I'd like to know if there is a more efficient way to do it?

Instead, you could leverage requests-futures to make asynchronous requests, construct the columns as lists of results and assign back to the DF. We have nothing to test with but the approach would look like this:

Install fastquery
You can use fastquery like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the fastquery component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
