So checking one the properties that cause one of these logs https://www.wikidata.org/wiki/Property:P4189 .. it has the value of 西藏和喜馬拉雅圖書館藏文轉寫 twice, in Chinese and Traditional Chinese. The lag is hit probably due to the fact that the current frontend will send separate requests per language. Effectively in this case sending a request for Chinese containing this value, that inserts it into master and another for Traditional Chinese that tries to insert again into master as replica hasn't caught up from the insert from previous request. Waiting on replication here won't solve the problem then, as it would wait on replication for current request changes as far as I understand the documentation. Our best option here seems to be silencing those errors. That should be fine as they are not persistent. Once replica catches up, they would not happen again unless similar situation for a new value (used twice across languages) appear in the same edit (causing such several requests with similar values).
