Kea1.7
- Kea 1.7 will focus on improving performance (number of leases served per second). This may include implementing support for multi-threading, depending on analysis of the technical options for performance improvement.
- Because of the continued strong interest among users for running Kea as a 'stateless' service, with a shared centralized lease database, in Kea 1.7 we will also look for ways to reduce contention between Kea servers handing out dynamic leases from shared pools by implementing multiple different address selection algorithms, or an offset from the next available address.
- 1.7 will update the D2 support in Kea, adding more fine-grained support for updating the DNS (or not updating it), for DDNS timer options equivalent to those in ISC DHCP, and for updating and removing DNS records. This should enable different DDNS policies for static host reservations vs dynamic reservations, and ideally also different policies for leases in different subnets. We should pay particular attention to verifying that DNS records are removed or updated as appropriate.
- Kea 1.7 will add support for the legacy bootp method for bootstrapping older devices. This is a requirement for some enterprises to implement Kea.
- To support the planned Kea management tool, we will add support for lease updates to an HA non-participating node. Kea's DNS integration must also be remotely manageable via this tool, which may require adding Kea-ctrl support to D2.
- As a stretch goal, we would like to add the capability to mark some address(es) as temporarily suspended from use.
