Field Description Default? Yes to make this strategy the default. Name The name for the strategy. Max Values The maximum number of values to allow in the merged property. Default is 99. Max Sources The maximum number of data sources from which to get values to merge. Source Weights The list of data sources and the weights assigned to them. Length Weight The weight assigned to the length of a string. - (Optional) Set Timestamp Path to the path to a timestamp field within the record.
This field is used to determine which values to include in the merged property, based on their recency, up to the maximum number specified in the Max Values field in Merge Options (Standard) or in Merge Strategies.
For example, if Max Values is set to 3, and five records meet the matching criteria, only the most recent three values will be included in the resulting record, and the two oldest values are ignored.
Note: Namespaces used in the path must be defined within the record. - Configure the Merge Collections.
