Hi Timur & Wesley,

Great to hear that Lock-free queues are successfully being used in
industry. Thanks again for the MoodyCamel reference.

I hope that all answers my question.

Really appreciate your support.

Once again, apologies all of you for polluting the SG14 mailing list with a
technical topic outside of SG14 discussion.

Best,
Honey
