Ephemeral Logs are generally used for short term communications. They will be stored in memory and do not survive a restart.
- These may need to be created and destroyed quickly, so it may be that they need to bypass a full creation service.
- When can you destroy an ephemeral log? Last close? What if there is a subscription keeping it open? Seems like some timeout is in order.
- Is there any need for a "sort of ephemeral" log, i.e., one that might survive a restart but only have a short lifetime? Is this any different from a regular log with an expiration?
