Question about large transactions

[hookumsnivy]

I'm using 5.0.2.RELEASE and processing large transactions - approximately 200k hsets.
I'm not interacting with lettuce directly, but instead through Spring Boot 2.0.0 and Spring Redis Data 2.0.5. Both were recent upgrades and I was using jedis in the past without a problem.
I'm not familiar with Lettuce at all, so please forgive my lack of understanding if I say something wrong.

Committing the transaction takes an abnormally long time (I haven't let it finish) and only the MULTI command has been written to Redis before I kill the process. I've stepped through the code and I think I may have found the culprit:

The addToStack method in CommandHandler. Before adding the command to the stack, it is checking to see if the command is already in the stack. This operation gets more and more expensive each time a command is added as it has to iterate through the entire stack each time.
Is this expected?
Is it necessary to make sure there aren't duplicates?

This issue was addressed with #709 and the fixed version is available as snapshot build 5.0.3.BUILD-SNAPSHOT. Care to upgrade and give the fix a try?
