   I think the direction to proceed for us, is to get to an agreement that this 
is worthy problem to solve.... few questions from my side, which can help:
   1. _Is the impact of event drops critical for the reliability of spark ?_ 
   [Note: By spark here I mean the base offering core+Dynamic allocation+App 
status etc]
   2. How common is event drop issue that one has got a complaint of from ones 
experience?
   3. What is general remedy one offers? ( it could be general strategy 
Databricks (or your company) offers to its customers)
   
   
   For the solutions part [if the issue is critical to solve]:
   1. what should be the general direction to solve such problems? 
[auto-detect=> auto-adjust=> auto-heal etc]
   2. How much user involvement is acceptable?
   
   If we have a quorum, we can decide what can be next steps......
