> 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
> - We will have information of current event ID and total number of events to replicate
for every event replicated.
