> 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.
