• All tests passed

Lab 2: Raft

Lab 3: Fault-tolerant Key/Value Service

• Build a fault-tolerant kv store based on the Raft protocol you've implemented with snapshot support
• All tests passed

Lab 4: Sharded Key/Value Service

• Build sharded fault-tolerant kv store based on the Raft protocol you've implemented with snapshot support
• I have passed all tests excluding TestChallenge1Delete

Development

• You should read the webpage of each lab for detailed information
• Some labs are broken into small parts and some labs and parts of a lab have dependencies on other labs and parts.
• You can checkout different branches to start doing these labs
• However PLEASE NOTE THAT THE CODE OF EACH BRANCH CAN ONLY PASS THE TEST OF IT'S BRANCH NAME AND THE PREVIOUS TESTS. For example, code of branch lab3b can only pass lab3b, lab3a and all lab2 tests. Code of branch lab3b may contain bugs for lab4
