Hello, I'm a bit confused with the purpose of Transaction Logs (Update Logs) in Solr.
My understanding is, update request comes in, first the new item is put in RAM buffer as well as T-Log. After a soft commit happens, the new item becomes searchable but not hard committed in stable storage. Configuring soft commit interval to 1 sec achieves NRT. Then what exactly T-Log is doing in this scenario? Why is it there and under what circumstances is it being cleared? I tried to search for online documentations but no success. Trying to get something from source code. Any hints would be appreciated.
