問題文
An architect places a Heroku app, its Postgres database, and Heroku Connect for an org hosted in Europe. Which placement decisions should be made, and why? (Select two.)
選択肢
- Keep Connect and Postgres in the same region and as close to the org as possible, because network latency becomes a significant factor in service performance.
- Plan to move the connection to a different Salesforce org later if the company consolidates its orgs, because a connection can be re-authenticated against another org once the existing mappings have been exported and re-imported.
- Set the database time zone to the region's local time so that timestamps match the org and comparisons between the two systems return the rows a report expects.
- Remember that a Connect instance is located in the same region as the application it is attached to, so the app's placement determines the instance's placement.
- Use the smallest available database plan, because latency dominates the cost of each operation and the number of rows has no bearing on how long a pass takes.
