Salesforce data replication also allows you to host identical data in multiple locations. This reduces lag seen by teams operating in vastly different geographic locations by moving a copy of the instance to a nearby server. This improves the performance of the network, user experience, and test system performance.
What is data replication in Salesforce?
The API supports data replication, which allows you to store and maintain an external, separate copy of your organization’s pertinent Salesforce data for specialized uses, such as data warehousing, data mining, custom reporting, analytics, and integration with other applications.
What is the difference between change data capture and replication data?
Data replication provides you with local control and the ability to run large or ad hoc analytical queries across the entire data set without transmitting all that data across the network. To get real-time notifications of Salesforce record changes, use Change Data Capture instead.
What are the benefits of replication tasks?
Explain the benefit of replication tasks. Replication is a Salesforce B2C Commerce process that pushes data and code from a staging instance to a development or production instance in a controlled manner, minimizing the risk of errors.
What is change data capture in Salesforce?
With Change Data Capture, you get broad access to data and can perform updates in your target store using transaction boundaries. Change Data Capture provides a versioned event schema and retains change events temporarily for later retrieval.

Does replication improve performance?
Putting a replica of the data closer to the user can improve access times and balance the network load. Replicated data can also improve and optimize server performance. When businesses run multiple replicas on multiple servers, users can access data faster.
What are the two advantages of data replication?
ADVANTAGES OF DATA REPLICATION – Data Replication is generally performed to: To provide a consistent copy of data across all the database nodes. To increase the availability of data. The reliability of data is increased through data replication.
What is data replication task?

What are the benefits and the drawback of replication?
The Synchronous Data Replication process writes data to its primary storage and to its replica server at the same time. This will allow you to replicate the data but it comes with 2 major drawbacks that are time and cost. To replicate data it is essential to confirm that all the data is written properly.
What are the three replication strategies?
Data Replication StrategiesStrategy 1: Log-Based Data Replication.Strategy 2: Full Table Data Replication.Strategy 3: Key-Based Incremental Data Replication.
Why is data replication bad?
The main disadvantage of key-based incremental replication is its failure to replicate already deleted data (since the data is deleted once the original is deleted). Note: Key-based incremental replication is also called key-based incremental data capture and key-based incremental loading.
What is the main benefit of replication when used with a system that is used for a lot of reporting such as marketing analysis queries?
Benefits of data replication Improve the availability of data. Increase the speed of data access. Enhance server performance. Accomplish disaster recovery.
What are the different types of replication?

What are the characteristics of a replication model?
The key characteristics defining the Replication operating model are: 1 Few, if any, shared customers 2 Independent transactions, aggregated 3 Operationally similar business units 4 Autonomous business unit managers with some discretion over processes 5 Centralized (of Federalized) control over business process design 6 Standardized data definitions, but locally owned with some aggregation 7 Centrally mandated Architecture services
What is the best operating model for replication?
The Replication operating model is best served by the Core Model architecture in which applications are centrally built and deployed locally. Features are enhanced locally with some added to core. The characteristics of the Core Model architecture type are:
Why is data replication used in production?
Because data replication is intended to push the latest version of a storefront into production, it’s a replace operation, and not a merge. Data replication first creates a copy of the data from the source instance at a new location in the target instance, without replacing the original data.
What happens when a recurring replication fails?
Be careful when you replicate. If a recurring data replication fails, subsequent repetitions of the job won’t run. Replication usually clears the page cache, which can have a dramatic impact on storefront performance.
Why is data replication important?
Because data replication is intended to push the latest version of a storefront into production, it’s a replace operation, and not a merge. Data replication first creates a copy of the data from the source instance at a new location in the target instance, without replacing the original data. When the process completes, you switch from the existing data to the new data in the target system, effectively replacing the data. It’s seamless and instantaneous.
How many ways can you schedule a replication process?
You can schedule a replication process four ways.
What is the purpose of replication?
While the main goal of replication is to push changes from staging to production, a preliminary step is to push the same changes to development. This lets you verify that replication was successful.
What is the purpose of Replicate the Code and Data?
Replicate the code (and data) to development to test the process.
What permissions do you need to limit who can perform data replication?
Use Business Manager permissions to limit who can perform data replication.

How to get real time notifications of Salesforce changes?
To get real-time notifications of Salesforce record changes, use Change Data Capture instead. By subscribing to a Change Data Capture channel, you receive a stream of change event messages for record changes, including insertions, updates, deletions, and undeletions. With Change Data Capture, you get broad access to data and can perform updates in your target store using transaction boundaries. Change Data Capture provides a versioned event schema and retains change events temporarily for later retrieval. For more information, see the Change Data Capture Basics Trailhead module, or for a complete reference, see the Change Data Capture Developer Guide.
Types of Events That Change Data Capture Can Generate: Change Events, Gap Events, and Overflow Events
Generally, Salesforce captures record changes by sending change events, which the subscriber receives to synchronize data in an external system. Sometimes, gap events or overflow events are generated.
Transaction-Based Replication Approach
Each change event contains a transaction key in the header that uniquely identifies the transaction that the change is part of. Each change event also contains a sequence number that identifies the sequence of the change within a transaction. The sequence number is useful for operations that include multiple steps, such as lead conversion.
How to Handle a Gap Event
If the event that the subscriber receives is a gap event, get the latest data from Salesforce. The gap event includes the ID of the affected record enabling you to retrieve the record.
How to Handle an Overflow Event
If a change results in more than 100,000 events in a single transaction, you receive overflow events for the events sent after the first 100,000. One overflow event is generated for each entity type. Mass changes aren't frequent.
Key Characteristics
Architecture Type: CORE Model
- The Replication operating model is best served by the Core Model architecture in which applications are centrally built and deployed locally. Features are enhanced locally with some added to core. The characteristics of the Core Model architecture type are: 1. Many apps 2. Same processes 3. Different data
Salesforce ORG Strategy
- Companies in the Replicationquadrant can (and probably should) have multiple orgs; you should consider deploying a package from a central org into all of the replicated BUs. That way you can provide local control/administration but maintain your pre-defined standard business processes.
