“UnityEditor.Sequences.SequenceAssetIndexer.InitializeWithExistingData” process runs on Domain Reload when there are more than 10000 Prefabs present
How to reproduce:
1. Open the “TestProject” project
2. Open the “Assets/TestScript.cs“ script in an IDE
3. Remove line 7 and save the file
4. Open the Editor and observe the Domain Reload process
Expected result: The “UnityEditor.Sequences.SequenceAssetIndexer.InitializeWithExistingData” process is completed within a second
Actual result: The “UnityEditor.Sequences.SequenceAssetIndexer.InitializeWithExistingData” process takes around 5-10 seconds to complete
Reproduced with: 1.1.0 (2021.3.36f1), 2.1.1 (2022.3.20f1, 2023.2.13f1, 2023.3.0b10)
Reproduced on: Windows 10, Windows 11
Not reproduced on: No other environment tested
Notes:
1. Sometimes the “UnityEditor.Sequences.SequenceAssetIndexer.InitializeWithExistingData” process window will appear after Domain Reload completes
2. Not reproducible in a project that has 1200 Prefabs
3. Changing the “Sequences” Package version causes a complete reimport of all the Prefabs

Resolution Note (fix version 1.1.0):
The InitializeOnLoad function was being called indiscriminately when the sequences package was installed without a sequence or sequence asset in the project. By saving an empty indexer, we avoid the unnecessarily expensive calls.
