Job parameters include:

• table : DB table to update
• column : The *_user_text column to update
• oldname : The old user name
• newname : The new user name
• count : The expected number of rows to update in this batch
• logId : The ID of the logging table row expected to exist if the rename was committed

Additionally, one of the following groups of parameters must be set: a) The timestamp based rename paramaters:

• timestampColumn : The *_timestamp column
• minTimestamp : The minimum bound of the timestamp column range for this batch
• maxTimestamp : The maximum bound of the timestamp column range for this batch
• uniqueKey : A column that is unique (preferrably the PRIMARY KEY) [optional] b) The unique key based rename paramaters:
• uniqueKey : A column that is unique (preferrably the PRIMARY KEY)
