[D] NER for large text data

Hello people
I am currently working as a data scientist at startup. We have a requirement of extracting entities from the text of 10 billion tokens. I am not aware how to do it at this much scale. What should be the pipeline and so on. It would be helpful if you guys share your knowledge or good research paper/blog. Currently we are working on 18 entities and my boss wants me to get 93% accuracy.
Thankyou
