2 Flexibility Solutions in Oracle GoldenGate Microservices
- Subset of Data
-
By replicating only relevant subsets of data, filtering can enhance replication speed and decrease the load and optimize performance on both source and target databases. The target table can be a subset of the source table, meaning that only specific rows or columns are replicated based on certain criteria.
-
Reducing Data Duplication / Data Reduction: Filtering and mapping can help prevent unnecessary duplication of data, maintaining cleaner datasets in the target environment. This is also minimizing storage costs and improves replication performance.
- Data Compliance and Security: Filtering can help ensure that sensitive or personally identifiable information is not replicated to less secure environments, helping organizations meet compliance regulations.
-
- Schema Adaptation
-
Mapping allows for changes in data structure, enabling the target database to have a different schema than the source. This is particularly useful when integrating with legacy systems or when the target system requires a different format.
-
Schema Compatibility: The target table should have a compatible schema with the source table to ensure that the data can be properly replicated. This includes data types and constraints.
-
Indexes and Constraints: While the target table can have different indexes or constraints, it's crucial to consider performance and data integrity when designing the target schema.
-
Partitioning: In some cases, the target may use a different partitioning scheme, which can help optimize performance for specific queries.
-
- Data Enrichment
-
Transformations can enhance the data during replication by adding calculated fields or converting data types, ensuring that the data is more useful for the target application.
- Consistency with Business Logic
- Transformations can enforce business rules and logic, ensuring that the replicated data aligns with the operational requirements of the target system.
- Improved Maintenance and Management
-
By tailoring the data through filtering and transformations, the target database can be optimized for specific use cases, leading to easier maintenance and management over time.
Incorporating filtering, mapping, and transformations allows organizations to tailor the replication process to their specific needs, enhancing efficiency, security, and data usability.
