Description

This is the log format that is being proposed for Hive Repl query logs

For bootstrap case:
Hive will log a message for each object as it is being bootstrapped and it will be in the following sequence

• Tables first (views are tables for this purpose) at time including partitions (depth first), followed by functions, constraints
• The ordering is based on the ordering of listStatus API of HDFS
• For each object, a message at the beginning of the replication will be logged
• Every partition bootstrapped will be followed by a message saying the number of partitions bootstrapped so far (for the table) and the partition name
• And a message at the end of bootstrap of an object

Incremental case:

• We will have DB Name, event id and event type will be part of the log header (for debugging/troubleshooting)
• We will have information of current event ID and total number of events to replicate for every event replicated.
