Introduction to Data Skew in Salesforce

In Salesforce, data skew is a critical concept that administrators and developers need to understand to maintain optimal performance and ensure smooth operations within the CRM environment. Data skew occurs when there is an imbalance in the distribution of data, which can lead to performance issues, record locking problems, and, in some cases, system errors. Understanding data skew, its types, and how to manage it effectively is crucial for the efficient administration of Salesforce orgs, especially as they grow in size and complexity.

Definition of Data Skew

Data skew in Salesforce refers to a situation where a disproportionate amount of data is associated with a particular parent record. This imbalance can cause various performance issues, especially in operations that require locking and sharing calculations. Data skew typically occurs in three main scenarios: ownership skew, lookup skew, and sharing skew. Each type has distinct characteristics and impacts on system performance.

Ownership Skew

Ownership skew occurs when a single user owns a large number of records. Salesforce recommends that a single user should not own more than 10,000 records to prevent performance issues.

For example, if a sales manager is assigned as the owner of over 50,000 customer records, every time the system needs to perform sharing calculations or when these records are updated, it may lead to significant performance degradation or record locking issues.

Implications of Ownership Skew

1. Performance Degradation: High volumes of records owned by a single user can slow down the system, particularly during data updates and sharing rule recalculations.
2. Record Locking Issues: Salesforce uses locks to ensure data integrity during updates. Ownership skew increases the likelihood of record locking conflicts, leading to errors and operational delays.
3. Increased Risk of Data Inconsistency: With frequent locks and performance lags, the chances of data inconsistency rise, potentially leading to inaccurate reporting and business decisions.

Managing and Preventing Ownership Skew

To effectively manage and prevent ownership skew, consider implementing the following strategies:

1. Distribute Record Ownership: Avoid assigning a large number of records to a single user. Distribute records more evenly among users to reduce the load on any one user.
   Best Practice: Use role hierarchies and territory management to distribute ownership based on geographic regions, product lines, or other logical segments.
2. Automate Ownership Transfers: Implement automated processes to reassign records periodically to ensure balanced distribution.
   Example: Use Salesforce’s built-in tools or custom Apex scripts to automatically reassign ownership based on predefined criteria.
3. Monitor Ownership Distribution: Regularly review ownership distribution reports to identify potential skews early.
   Tool: Utilize Salesforce reports and dashboards to monitor the number of records owned by each user.
4. Leverage Queues: Use queues to handle large volumes of records instead of assigning them to individual users.
   Application: For cases or leads, assign records to a queue where multiple users can take ownership and action, preventing skew.
5. Review Sharing Rules: Ensure sharing rules are optimized to minimize the impact of ownership skew on performance.
   Strategy: Use criteria-based sharing rules to target specific subsets of records rather than broad, inclusive rules that affect a large number of records.

Lookup Skew

Lookup skew happens when a large number of records have a lookup field that points to the same parent record. This can create performance bottlenecks during DML operations and can lead to locking conflicts.

For example, suppose an account record is linked to 30,000 contacts through a lookup relationship. Whenever an update operation occurs on any of these contacts, Salesforce needs to lock the parent account record, potentially causing delays and lock exceptions.

Implications of Lookup Skew

1. Performance Bottlenecks: A high number of lookup relationships to a single parent record can slow down the system, especially during update operations.
2. Record Locking Conflicts: When multiple child records are updated simultaneously, the parent record may become locked, leading to conflicts and delays.
3. Delayed Operations: Due to the locking of the parent record, operations on child records can be delayed, impacting user productivity and system performance.

Managing and Preventing Lookup Skew

To manage and prevent lookup skew, consider the following approaches:

1. Distribute Lookup Relationships: Ensure that lookup relationships are distributed more evenly across multiple parent records.
   Best Practice: Design your data model to avoid excessive lookup relationships to a single parent record.
2. Use External IDs: Where possible, use external IDs to link records instead of lookup fields, reducing the reliance on a single parent record.
   Application: Use external IDs in integration scenarios to reference records without creating lookup skew.
3. Optimize Data Model: Regularly review and optimize your data model to identify and address potential lookup skew issues.
   Tool: Utilize Salesforce Schema Builder and reports to analyze relationships and adjust as necessary.
4. Leverage Asynchronous Processes: For operations involving a large number of records, use asynchronous processes such as future methods, batch Apex, or scheduled jobs to minimize the impact on real-time performance.
   Example: Use batch Apex to process updates in smaller chunks, reducing the load on parent records.

Sharing Skew

Sharing skew occurs when a large number of records are associated with a particular sharing rule or when many records are shared with the same group of users. This skew can cause performance issues during sharing recalculations.

For example, if a custom object has a sharing rule that applies to 20,000 records, and this rule is set to share records with a large public group, any changes to the sharing rules or the group composition can trigger extensive sharing recalculations, impacting performance.

Managing Data Skew

To effectively manage data skew, it is essential to:

1. Monitor and Analyze: Regularly review data distribution and monitor for signs of skew, such as frequent locking issues or slow performance during DML operations.
2. Distribute Data Evenly: Avoid having too many records owned by a single user or associated with a single parent record. Distribute records more evenly across users and parent entities.
3. Optimize Sharing Settings: Carefully design sharing rules and public groups to minimize the impact of sharing skew. Use criteria-based sharing rules to target specific subsets of records instead of broad sharing rules.
4. Use Asynchronous Processes: Where possible, use asynchronous processing (such as future methods, batch Apex, or scheduled jobs) to handle large data operations, reducing the impact on real-time performance.

What is Account Data Skew?

Account data skew happens when an excessive number of child records (such as contacts, opportunities, or custom object records) are linked to a single account. Salesforce recommends that no single account should have more than 10,000 child records to prevent performance degradation and potential locking issues. This imbalance can cause significant delays and errors during data operations due to the high volume of records that need to be processed simultaneously.

Example of Account Data Skew

Consider a scenario where a large enterprise account is associated with 50,000 contacts. Whenever an update is made to this account or any related contact, Salesforce needs to perform sharing recalculations and may lock the parent account record. This locking mechanism ensures data integrity but can create bottlenecks, resulting in slower performance and potential system errors.

Implications of Account Data Skew

1. Performance Degradation: When an account has too many child records, any updates to the account or its child records can significantly slow down the system. The high volume of data requires extensive processing, which can impact overall performance.
2. Record Locking Issues: Salesforce uses a locking mechanism to maintain data consistency during updates. Account data skew increases the likelihood of record locking conflicts, where multiple processes attempt to access and update the same account simultaneously. This can lead to operational delays and errors.
3. Sharing Recalculations: Changes to sharing rules or record ownership can trigger extensive sharing recalculations for accounts with a large number of child records. This can consume considerable system resources and time, further impacting performance.
4. Data Inconsistency Risks: Frequent locks and performance lags increase the risk of data inconsistencies. Delays in processing can lead to outdated or inaccurate data being presented to users, affecting business decisions and reporting.

Managing and Preventing Account Data Skew

To effectively manage and prevent account data skew, consider implementing the following strategies:

1. Distribute Child Records: Avoid associating too many child records with a single account. Distribute child records more evenly across multiple accounts to reduce the load on any one account.
   Best Practice: Create logical partitions of data based on regions, business units, or product lines to distribute child records across different accounts.
2. Optimize Data Model: Regularly review and optimize your data model to identify and address potential account data skew issues.
   Tool: Use Salesforce Schema Builder and reports to analyze the number of child records associated with each account and make necessary adjustments.
3. Leverage Asynchronous Processes: For operations involving a large number of records, use asynchronous processes such as future methods, batch Apex, or scheduled jobs to minimize the impact on real-time performance.
   Example: Use batch Apex to process updates in smaller chunks, reducing the load on parent accounts.
4. Monitor Account Relationships: Implement monitoring to regularly check the number of child records associated with each account and take proactive measures to redistribute records if necessary.
   Tool: Utilize Salesforce reports and dashboards to monitor account relationships and identify potential skew.
5. Review Sharing Rules: Ensure that sharing rules are optimized to minimize the impact of account data skew on performance. Use criteria-based sharing rules to target specific subsets of records rather than broad sharing rules.
   Strategy: Design sharing rules that apply only to necessary records, reducing the number of recalculations required.
