Detailed Description

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)
  • keyId : A list of values for this column to determine rows to update for this batch

To avoid some race conditions, the following parameters should be set:
