What is skinny table in salesforce?

Hi Piyush,

Salesforce can create skinny tables to contain frequently used fields and to avoid joins. This can improve the performance of certain read-only operations. Skinny tables are kept in sync with their source tables when the source tables are modified.

Skinny tables can contain the following types of fields.

• Checkbox
• Date
• Date and time
• Email
• Number
• Percent
• Phone
• Picklist (multi-select)
• Text
• Text area
• Text area (long)
• URL
