Creating a new community on its dedicated shard would be tested and working, including assigning a pre-shared key for opt-in message signing (weak DoS protection).
Community creation on a default shard (32) to remain (up to app team to hide button or not) to enable mass creation of communities on shared shard for QA testing purposes.
Vac QA and DST are asked to look at Status Communities behaviour, whereas previously the focus was on direct messages reliability (one layer lower).
Finally, telemetry service will be updated to include bandwidth usage statistics, with a fine breakdown to understand top bandwidth consumers (control msg, chat msg, etc). Additionally, the DST team is asked to run simulations with a focus on bandwidth usage.
Add bandwidth measurements to the self-report (opt-in) telemetry service, including a message type breakdown (ctrl, chat, etc) when possible as well as other protocols such as discovery.
Usage of non-waku bandwidth should also be considered (bittorrent, RPC) to have a full picture in case of report of high bandwidth usage by users.
### Deliverable: [Sharding peer management and discovery hardening](https://github.com/waku-org/pm/issues/172)
Further testing and improvement of peer management in the context of sharding in all Waku implementations. The aim is to ensure that nodes are connected to other nodes of interested shards. As the number of shards (several communities) increase, some improvement on the logic should be needed.
(1) nwaku and go-waku need to follow the same pattern here in terms of relay peer management. For Relay peer management:
- remove named sharding to simplify peer management
- review per-shard peer management metrics (e.g. mesh health per subscribed shard)
- monitor and adapt peer management strategy across both go-waku and nwaku for various shard subscription scenarios (e.g. up to 100 pubsub topic subscriptions) in an integrated deployment
(2) go-waku and nwaku should also follow the same patterns in terms of managing filter/ligh tpush clients (i.e. always keep a predictable amount of open slots for clients) with similar steps to the above to harden the strategy
(3) go-waku and js-waku should follow the same patterns in terms of managing service peers within clients.
(4) Capture recommendations in an RFC and use it as a discussion and decision medium across implementations.
### Deliverable: [Enable testing of custom shard implementation for Communities](https://github.com/waku-org/pm/issues/196)
Create/update CLI with REST API to enable creation and usage of static communities on own dedicated shard for Vac/QA to proceed with testing of various scenarios.
This CLI should also enable running simulations of bandwidth usage by communities, including ctrl messages.
This includes the setup of a pre-shared key to protect the shard and fixing any bug reported.
Note that the ability to create communities on a custom shard and assign a pre-shared key for DoS protection is already implemented in status-go.
Note that telemetry service should include shard specific reports.
### Deliverable: [Setup Waku Community on dedicated shard with pre-shared key dos protection](https://github.com/waku-org/pm/issues/262)
Create a Waku token-gated community on its own dedicated shard to further dog food sharding, find and fix any Waku related bugs as well as providing support to the Status app team.
The outputs of this deliverable are:
- Waku token-gated community created on dedicated shard. While this community may not be advertised publicly at first, it will be set up as if, with Waku CC and IFT CCs roles being defined etc.
- Document that summarises the steps to setup a dedicated community, where IFT devops are provisioning the new shard, and setting pre-shared key in coordination with community owner.
With phase 1, feedback from test stressing and IFT CC has been tackled.Preparation has been done to consult an external agency to fine tune PostgreSQL setup.
Phase 2 tracks the consultation with the external agency and follow-up work:
- Once all suggestions from IFT PostgreSQL expert are implemented, setup an agreement with consulting agency specialised in PostgreSQL performance to improve performance
This should include a better understanding of hardware requirements expectations to run Waku infra for Status.
