Question
You are given a list of VM_Vehicles Custom Data Types (CDT).
Which smart service offers the best performance to write the values to the database?
A. Write to Data Store Entity
B. Write to Multiple Data Store Entities
C. Sync Records
Answer
The best-performing smart service for writing a list of Custom Data Types (CDT) to the database in Appian is:
A. Write to Data Store Entity
Explanation
The Write to Data Store Entity smart service (Option A) is specifically designed to efficiently write one or more instances of a CDT into a single data store entity, which corresponds to a database table. This service excels in performance due to its streamlined process of interacting directly with the database to handle bulk inserts and updates. It works by leveraging optimized database operations, making it suitable for writing large datasets such as a list of VM_Vehicles CDTs.
Why Not the Other Options?
B. Write to Multiple Data Store Entities:
This smart service is used when you need to write to multiple entities or tables simultaneously. However, it requires more processing overhead as it performs multiple operations across different tables, reducing performance compared to Write to Data Store Entity when only a single data store entity is involved. If you are writing data to just one entity (as in this scenario), this option is unnecessarily complex and slower.
C. Sync Records:
The Sync Records smart service is specifically used to sync data between an external system and Appian’s record system, not for writing CDTs directly into the database. It is intended for situations where you need to ensure that records within Appian are in sync with external data sources, not for direct database inserts. Therefore, it is not suitable for this task.
For writing a list of VM_Vehicles CDTs to a single database entity, Write to Data Store Entity offers the best performance. It is optimized for bulk writing operations and avoids the overhead of writing to multiple entities or syncing records unnecessarily.
