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...

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...

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...

Is it possible to add a new metrics for projection execution time?

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.

Read only start up mode

Have to ability to start a single node EventStore in complete read-only mode. This will allow the rebuilding of corrupted indexes on a different server from a production backup without worrying about surpassing the production checkpoint due to new...

Adjust the Log levels

At the moment the default log level is Debug, because lots of important logging is currently at the debug level. Users understandably sometimes raise the level to Information and miss important logs We should review and adjust the log levels of al...

Make the scavenge.db file take up less space

At the moment it has to detect and track stream hash collisions, but it would be possible to track these more easily in the database itself (without taking additional space) and remove the significant bulk of scavenge.db. It may also make the accu...

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...

Crypto-assurance for audit

Crypto-assurance provides guarantees against mutations, truncation, and reordering. Although ESDB doesn't provide nativa mutation and reordering capability, data on disk can be tampered to change the content of events. ESDB supports truncation wit...
