A Matchgrid is the core element of the matching system, and represents a single tenant within a multi-tenant deployment. Matchgrids are configured by the Platform Administrator.
The unique identifier assigned to an individual within a Matchgrid is called the Reference Identifier. Match supports two methods for assigning Reference Identifiers:
- Sequence: An incrementing integer, equivalent to a database SERIAL
- Sequences must be assigned a starting number. Reference Identifiers created by this method are not padded, so to generate (for example) 8 digit identifiers, set the starting number to 10000000.
- Sequences may optionally be assigned a prefix string, such as
MRID. This will result in Reference Identifiers such asMRID1001(depending on what the starting number is.)
- UUID (Type 4)
If the Reference Identifier assignment method is changed, existing identifiers will not be affected. The new configuration will only be applied to newly assigned Reference Identifiers.
When the Matchgrid is built (after the Matchgrid attributes and rules are defined), a new database table will be created using the name of the Matchgrid, prefixed with mg_.
