Chained replicas

Current implementation of read-only replicas require them to be connected to the cluster. It means that every new replica adds some overhead to the operational cluster nodes, particularly its leader. It creates limitation of the feature as one mig...

Delete streams without a trace

Customers who actively clean up their database encounter a situation when the scavenge.db file grows uncontrollably because it keeps the information about stuff that has been deleted. Eventually, it might lead to a situation when the scavenge.db f...

Schema registry

Have a component that would allow developers to register their events schema in the registry. When appending new events, when the schema id is provided, the event is checked for compatibility with the schema, and it it's not compatible, the append...

Read only replicas with single-node databases

Consider allowing read only replicas to connect to single node deployments. Currently, this is not possible because replication is disabled on single node databases.

Server-side read models

It would be cool if we could take the users code and run it 'serverside' (meaning, in the nodes or in sidecars) the read models could be in memory, or persisted in one of a small selection of built in stores (stream store, kv store, relational sto...

Support certificates with EC (elliptic curve) keys

ESDB currently supports only RSA keys in certificates when specifying --certificate-private-key-file. The advantage of using EC keys would be that the key is much smaller for the same security level (EC takes 256 bit vs RSA 2048 bit for same secur...
