Final answer:
The "colddb" folder contains the cold bucket, while the thawed bucket is stored in a separate folder. The contents of the thawed bucket depend on the application.
Step-by-step explanation:
The "colddb" folder inside defaultdb contains the cold bucket in a database.
The thawed bucket is stored in a different folder, typically named "thawedb" or something similar.
The contents of the thawed bucket can vary depending on the specific application or use case, but it generally includes data that has been processed or transformed in some way.
