Fix sync flow throttling: default admin_DelayObjectInventory to "yes"

[Copilot]

Sync flows (v3 Flow Action Details, v4 Flows) run 7+ hours instead of 30-120 minutes when the Driver triggers 20+ child flows concurrently. Without delays, concurrent API calls exceed Dataverse limits (6,000 req/5min), causing exponential retry backoff that extends runtime by hours.

Changes

Environment Variable Default

• admin_DelayObjectInventory: no → yes
• Spreads environment processing over time, preventing throttling
• Existing installations unaffected (use current values, not defaults)

Documentation

• New TROUBLESHOOTING-FLOW-PERFORMANCE.md: root cause analysis, resolution steps, runtime benchmarks
• Updated README.md: added FAQ entry, updated environment variable table
• Added issue response template for flow performance issues
• Consistency updates across existing docs

Technical Detail

Counterintuitive fix: Adding randomized delays (1-5min) between environment inventories makes flows complete faster by avoiding throttling retries. Without delays, flows hit API limits → retry with exponential backoff (1min → 2min → 4min → 8min...) → cascading delays across all concurrent flows.

Migration Path

Existing installations experiencing this issue:

admin_DelayObjectInventory = Yes
admin_DelayInventory = Yes (already default)
admin_FullInventory = No (unless doing initial inventory)

Expected runtime: 30-90 minutes (v4 Flows), 1-2 hours (v3 Flow Action Details)

• I have checked and confirm this is a new bug.

Describe the issue

Admin | Sync Template v3 (Flow Action Details) in this for some environments it is in Running state for long more than 7 hrs.
Also the
Admin | Sync Template v4 (Flows) . Both are triggered on the environment table change and might be that is causing the throttle..

Expected Behavior

Should complete the flow in max 1 hour-...as before

Comments on the Issue (you are @copilot in this section)

@mohamrizwa Hi @Naz931, Thank you for reporting this issue. After analyzing the flow definitions and architecture, the 7+ hour runtime is caused by **API throttling from concurrent flow executions**, not a bug in the flows themselves.

🎯 Immediate Solution

1. Enable throttling prevention settings:

   • Navigate to Power Apps → Solutions → Center of Excellence - Core Components → Environment Variables
   • Find admin_DelayObjectInventory and set Current Value = Yes
   • Find admin_DelayInventory and set Current Value = Yes

2. Verify inventory mode:

   • Find admin_FullInventory and verify Current Value = No (for regular scheduled runs)

3. Allow settings to take effect:

   • Changes apply on the next Driver run

📊 Expected Results

With delays enabled and incremental mode:

• v4 Flows: 30-90 minutes (depending on tenant size)
• v3 Flow Action Details: 1-2 hours (processes more detailed data)

🔍 Why This Happens

When the Driver flow updates environment records, it triggers 20+ child flows simultaneously. Without delay settings, this creates thousands of concurrent API calls that exceed Dataverse throttling limits (6,000 requests per 5 minutes). The flows then retry with exponential backoff, extending runtime from minutes to hours.
