I have some very specific requirements, including, but not limited to:
- control over the entirety of the relay “frontend”: this is primarily to process filters, for example, directing them to different DBs or modifying
- support for multiple sub-partitions of the same DB
- attaching custom data to events
- control of query execution for limits
- custom handling of event replacement and deletions
- support for swappable KV backend
- support for multiple instances running on different hosts on the same KV DB
