Hi Jamie,

The most relevant materials I can think of would be in KIP-101:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-101+-+Alter+Replication+Protocol+to+use+Leader+Epoch+rather+than+High+Watermark+for+Truncation

Although it is a bit out-dated it still contains most significant design
key ideas here.
