> It is necessary to log the progress the replication tasks in a structured manner as follows.
> *+Bootstrap Dump:+*
> * At the start of bootstrap dump, will add one log with below details.
> {color:#59afe1}* Database Name
> * Dump Type (BOOTSTRAP)
> * (Estimated) Total number of tables/views to dump
> * (Estimated) Total number of functions to dump.
> * Dump Start Time{color}
> * After each table dump, will add a log as follows
> {color:#59afe1}* Table/View Name
> * Type (TABLE/VIEW/MATERIALIZED_VIEW)
> * Table dump end time
> * Table dump progress. Format is Table sequence no/(Estimated) Total number of tables
and views.{color}
> * After each function dump, will add a log as follows
> {color:#59afe1}* Function Name
> * Function dump end time
> * Function dump progress. Format is Function sequence no/(Estimated) Total number of
functions.{color}
> * After completion of all dumps, will add a log as follows to consolidate the dump.
> {color:#59afe1}* Database Name.
> * Dump Type (BOOTSTRAP).
> * Dump End Time.
> * (Actual) Total number of tables/views dumped.
> * (Actual) Total number of functions dumped.
> * Dump Directory.
> * Last Repl ID of the dump.{color}
> *Note:* The actual and estimated number of tables/functions may not match if any table/function
is dropped when dump in progress.
> *+Bootstrap Load:+*
> * At the start of bootstrap load, will add one log with below details.
> {color:#59afe1}* Database Name
> * Dump directory
> * Load Type (BOOTSTRAP)
> * Total number of tables/views to load
> * Total number of functions to load.
> * Load Start Time{color}
> * After each table load, will add a log as follows
> {color:#59afe1}* Table/View Name
> * Type (TABLE/VIEW/MATERIALIZED_VIEW)
> * Table load completion time
> * Table load progress. Format is Table sequence no/Total number of tables and views.{color}
> * After each function load, will add a log as follows
> {color:#59afe1}* Function Name
> * Function load completion time
> * Function load progress. Format is Function sequence no/Total number of functions.{color}
> * After completion of all dumps, will add a log as follows to consolidate the load.
> {color:#59afe1}* Database Name.
> * Load Type (BOOTSTRAP).
> * Load End Time.
> * Total number of tables/views loaded.
> * Total number of functions loaded.
> * Last Repl ID of the loaded database.{color}
> *+Incremental Dump:+*
> * At the start of database dump, will add one log with below details.
> {color:#59afe1}* Database Name
> * Dump Type (INCREMENTAL)
> * (Estimated) Total number of events to dump.
> * Dump Start Time{color}
> * After each event dump, will add a log as follows
> {color:#59afe1}* Event ID
> * Event Type (CREATE_TABLE, DROP_TABLE, ALTER_TABLE, INSERT etc)
> * Event dump end time
> * Event dump progress. Format is Event sequence no/ (Estimated) Total number of events.{color}
> * After completion of all event dumps, will add a log as follows.
> {color:#59afe1}* Database Name.
> * Dump Type (INCREMENTAL).
> * Dump End Time.
> * (Actual) Total number of events dumped.
> * Dump Directory.
> * Last Repl ID of the dump.{color}
> *Note:* The estimated number of events can be terribly inaccurate with actual number
as we don’t have the number of events upfront until we read from metastore NotificationEvents
table.
> *+Incremental Load:+*
> * At the start of incremental load, will add one log with below details.
> {color:#59afe1}* Target Database Name 
> * Dump directory
> * Load Type (INCREMENTAL)
> * Total number of events to load
> * Load Start Time{color}
> * After each event load, will add a log as follows
> {color:#59afe1}* Event ID
> * Event Type (CREATE_TABLE, DROP_TABLE, ALTER_TABLE, INSERT etc)
> * Event load end time
> * Event load progress. Format is Event sequence no/ Total number of events.{color}
> * After completion of all event loads, will add a log as follows to consolidate the load.
> {color:#59afe1}* Target Database Name.
> * Load Type (INCREMENTAL).
> * Load End Time.
> * Total number of events loaded.
> * Last Repl ID of the loaded database.{color}
