What is ServiceNow Data Replication: Seamless Third-Party Connectivity

What is Data Replication

Data is the backbone of information and knowledge, making it imperative to maintain accuracy and integrity. Data replication stands as a key method for safeguarding this vital asset. It involves creating multiple copies of data, ensuring each replica remains synchronized, reliable, and resilient in real time.

Organizations employ data replication to ensure that users have immediate access to the most current and authentic information. This redundancy of copies not only facilitates seamless access but also serves as a safeguard against potential disruptions. Even if one copy becomes inaccessible, users can still retrieve the necessary information with minimal delay and without significant data loss.

There are various types of data replication methodologies. Synchronous replication involves replicating every original data operation in real time, ensuring that each copy remains identical. On the other hand, asynchronous replication allows for a delay between data updates and replication, typically occurring after the statement is passed to the database. Both approaches offer distinct advantages and are chosen based on specific organizational needs and priorities.

Data Replication vs Data Synchronization

Although data replication and data synchronization are frequently used interchangeably, they carry distinct meanings and serve different purposes. While they can be used together or separately depending on the context, it’s essential to grasp their unique characteristics.

  • Data replication implies that there are two or more copies of all the data simultaneously, while data synchronization means that the copies of data are being kept updated, but each copy does not necessarily contain all of the data. 
  • Data synchronization can save space, transfer only the changes, and provide consistent data, while data replication can need more space to copy all the data and provide stable and available data.

How Data Replication Works

How Data Replication Works

Data replication is critical in data synchronization and system integration, enabling seamless data exchange between disparate systems. By configuring replication rules, organizations can precisely control the synchronization of tables and their respective columns.

The data replication process offers flexibility regarding directionality, scheduling, and event triggers. It can operate in one or two directions, facilitating real-time data exchange and effectively managing operations across multiple regions. Additionally, it allows the segregation of business unit-specific data while enabling occasional collaboration and ensuring data recovery during disasters.

Data Replication Process

By following these steps, organizations can effectively implement data replication processes, ensuring seamless synchronization and integration across their systems while maintaining data integrity and consistency.

1. Use Data Replication Plugin: Begin by deploying the data replication plugin to initiate the replication process from one instance to another.

2. Configure Producer Replication Set: Define a producer replication set, specifying the tables and columns to be replicated.

3. Activate Producer and Consumer Replication Sets: Enable both producer and consumer replication sets to configure data updating. It includes performing a one-time download, or seeding, of all producer data to the consumer.

4. Apply Filter Options: Activate the consumer replication set and utilize the filter criterion feature to specify the number of seeded records.

5. Implement Partial Seeding: Employ partial seeding to manage large numbers of records more efficiently, dividing them for replication.

6. Utilize Audit Trail: Monitor the history of updates using the audit trail feature, ensuring transparency and accountability in the replication process.

7. Implement Transformation: Employ transformation techniques to replicate data from the producer source to tables with different names on the consumer source.

8. Use Data Replication Adapters: Before storing it on the consumer source, utilize data replication adapters to modify data, such as time zone adjustments or currency conversions.
