Cloud Pak for Data Version 4.7.1
A new version of IBM Match 360 was released in July 2023 with Cloud Pak for Data 4.7.1.
- Operand version: 3.1.25
- CASE version: 3.1.0
This release includes the following changes:
- New features
-
The 3.1.25 release of IBM Match 360 includes the following features and updates:
- Help prevent the creation of low-quality entities by defining glue record thresholds
- This release of IBM Match
360 introduces a
new glue record threshold configuration to help prevent the creation of poor quality entities. When
IBM Match
360 forms entities through matching,
some low-quality records can act as glue records. Because the records are not very
detailed, glue records can appear to match with many different records. This matching behavior
inadvertently and incorrectly creates very large entities that have only one low-quality glue record
in common.
By setting a glue record threshold in the matching algorithm for each entity type, a data engineer can prevent glue records from causing the formation of large, poorly matched entities. For more information, see Configuring a glue record threshold.
- Finer control over which records are considered for matching
- You can now define filters that determine which records are considered during the matching
process. By default, all records associated with the entity’s record type are considered during
matching. However, with record filtering, you can create rules that remove unwanted
records from consideration, based on their attribute values.
For example, if you are matching person entity data but want to match only records that are based in the United States, you can define a record filter on the Country attribute so that the matching engine considers only records with US-based addresses.
For more information, see Selecting which records get considered for matching and Matching algorithms > Entity types (bucketing).
- More control over how entities select attribute values from member records
- With the enhanced attribute composition capabilities, data engineers have more control over how
the attribute values for master data entities are selected from the entity's member records. You can
now define filter and sorting conditions that control which records are considered and how
attributes are selected for an entity. For attributes that can potentially include more than one
value, such as a list, you can configure the maximum number of values.
By defining and prioritizing a set of rules, filters, and other conditions, you have more control over which record attribute values are surfaced to the entity. For more information, see Defining attribute composition rules.
- Bug fixes
-
The 3.1.25 release of the IBM Match 360 service includes the following fixes:
- Issue: When viewing master data in an IBM Match
360 connection asset, row filter masking rules do
not
work.Resolution: Row filter masking rules are now correctly applied to IBM Match
360 connection assets. - Issue: While upgrading IBM Match
360,
Elasticsearch pods can remain in a
1/2 Running
state, causing IBM Match 360 to remain in anInProgress
state.Resolution: The configuration of IBM Match
360 was updated to resolve this issue. - Issue:
IBM Match
360 requires special configuration to
load data from MDM
Publisher.Resolution: Required configuration steps are now part of MDM Publisher setup and configuration. For more information, see the InfoSphere MDM documentation.
- Issue: When exporting record or entity data from IBM Match
360 by using the master data explorer UI, the
export fails if the resulting file is larger than 512
MB.Resolution: The file size limitation was removed.
- Issue: When exporting record or entity data from IBM Match
360 by using the API, the export fails if the
resulting file is in ZIP format and larger than 4
GB.Resolution: The file size limitation was removed.
- Issue: A timeout error can occur in successful offline backup and restore
operations.Resolution: The timeout configuration was changed to help prevent this issue from occurring.
- Issue:
IBM Match
360 connections do not support secrets
from
vaults.Resolution: Secrets from vaults are now supported with specific configurations. To use vaults, you must use keys to create credentials in the vault.
- Issue: When viewing master data in an IBM Match
360 connection asset, row filter masking rules do
not
work.

Cloud Pak for Data Version 4.7.0
A new version of IBM Match 360 was released in June 2023 with Cloud Pak for Data 4.7.0.
- Operand version: 3.0.55
- CASE version: 3.0.18
This release includes the following changes:
- New features
-
The 3.0.55 release of IBM Match 360 includes the following features and updates:
- New data quality workflow helps data stewards remediate potential match issues
- Use the new IBM Match
360
potential matches workflow to fix potential matching issues in your master data.
Streamline your data stewards' workflow by defining the range of matching scores that qualifies for
clerical review, then create governance tasks to help data stewards make decisions that enhance
confidence in your master data.
The potential matches workflow provides the framework that data stewards can use to:
- Quickly generate governance tasks for potential matching issues in your data or a subset of your data.
- Review and remediate the generated tasks by making match or no-match decisions on records for which the matching algorithm cannot make a confident matching decision.
For information on configuring the potential matches workflow, see Configuring master data workflows.
For information on identifying, reviewing, and remediating potential match issues, see Remediating potential matches to improve data quality.
- New data quality dimension measures entity confidence
- IBM Match
360 now contributes a new
entity confidence data quality dimension to the Data quality tab
for an asset in a project. Entity confidence measures the percentage of master data entities in the
system that IBM Match
360 is confident are
complete and accurate. You can improve an asset's entity confidence score by tuning your matching
algorithm or remediating potential match issues.
For more information about entity confidence, see Remediating potential matches to improve data quality.
- IBM Match 360 protects sensitive data according to governance rules
- When you associate IBM Match
360 with a
governed data catalog that uses data protection rules, IBM Match
360 enforces the rules by masking sensitive
data.
When you are working with governed data assets in the master data explorer, a shield icon on an attribute name indicates that its values are masked by a data protection rule. Governed data is also protected when it is accessed through the IBM Match 360 API.
For more information about using data protection rules with IBM Match 360, see Working with governed data in IBM Match 360.
- Stream change events from your master data to downstream systems
- Now IBM Match
360 can, in real time,
propagate changes in your record and entity data directly to downstream systems through a connected
Apache Kafka server. Streaming ensures that your
users and systems always have the freshest and most up-to-date master data. Master data streaming is
available only through the IBM Match
360 API.
For more information, see Streaming record and entity data changes.
- Define entity attributes that persist with entities
- This release introduces a new type of attribute that is saved directly on your master data
entities, rather than being composited from their member records. Customize the data model of your
entity types to add new entity attribute definitions, then edit individual entities to specify the
attribute values.
Rather than relying on only record data to provide entity attribute values, the ability to specifically define entity attributes gives organizations the flexibility to store, capture, and manage digital twin attributes for each entity to better track behavior indicators, engagement preferences, and other key customer data points.
For more information about entity attributes, see Data concepts in IBM Match 360.
