Consistency policies

One of the main concerns developers have about impoementing Event Sourcing is so-called "eventual consistency". It means that when a system implements one or more query models either in ESDB using custom projections or in other databases using cat...

Timestamp-based reads

For temporal and bi-temporal models it would be beneficial to be able to read streams, as well as start subscriptions, using timestamps instead of positions. It would allow answering questions "what happened after that date and time, before this d...

Filtered reads and subscriptions to streams

ESDB currently allows filtered subscriptions to $all. The idea is to support filtered reads from $all, from streams, as well as filtered catch-up subscriptions to streams.

Support running ESDB on ARM64 Linux distributions

Substantial population of developers use Apple computers with ARM chip, and they currently cannot run ESDB locally even in Docker. We do have an "alpha" image but nobody gives any guarantees that everything works there. By providing a supported im...

Support authorisation when reading from $all

Currently, reads and subscriptions to $all require admin access, which isn't good for security. Supporting auth for $all will have performance impact when ACLs are used, but in combination with policies it could be fast enoguh because policies, un...

Stream authorisation policies

ESDB has access control lists (ACLs) as the primary method to achieve granular (per stream) authorisation. However, ACLs need to be set up per stream, which is a burden for developers. Also, if the auth rules change, all the streams need to get th...
