Interesting to hear about forks out there running in production.

WRT the meet-up, things we’d be happy to talk about/like to discuss if there’s time on the agenda. We’d be able to give talks/lead discussions on these topics:

- Repl, Rabl, AAE, and Fullsync
- Leveled
- New indexing and querying and the future CRDT work
- A review of the estate from the NHS POV (tech debt, OTP20, Build and release etc)

>>  Hi,
>> We are beginning to plan out the two day workshop [1]. We are thinking the first day will start with an introduction from Martin Davies, in which Martin will detail current status and the asset list.
>> After which we will get into project questions, such as:
>> Which license?
>> The general consensus is Apache2. We need to complete the discussion as HyperLogLog has been introduced which is GPL’d. Our thoughts are to replace HLL.
>> Baseline?
>> We have heard some discussion around where to baseline the codebase. The concern is during the demise of Basho the correct level of diligence was not applied to promotes meaning the code such as HLL has crept in.
>> Governance?
>> How are we to manage the project going forward? Our feeling is we do not need a formal body as being discussed in the slack group. We see the project going forward as a simple repo into which likeminded developers agree and contribute changes. Placing overbearing procedure and structure on what is currently a small community will dissuade other from joining and contributing.
>> Supporting infrastructure.
>> The Basho websites, github account, and mailing group are all included in the deal. We are currently supporting the mailing list, and once the deal is complete we will continue to support the Basho domains; restricting community disruption.
>> Roadmap
>> Below, in no particular order, are the items we wish to address internally. If we can all share our lists we can come to an agreed community roadmap between us.
>> ·         Review / rationalisation of Basho JIRA tickets / git issues
>> ·         Replication
>> o    Address known issues (30+) to add stability
>> o    Selective replication
>> o    Persistent realtime queue
>> o    Review of general approach
>> §  In / out of band
>> §  Snapshot vs deltas
>> ·         General
>> o    Address known issues (20+) to add stability
>> o    Silent data loss bug in riak_kv
>> ·         Enhancements
>> o    G Sets
>> o    Big Sets
>> o    CRDT Maps
>> o    Async read / write vnodes
>> o    Split backend vnodes
>> o    Head requests – don’t return body to co-ordinator
>> o    Rudimentary indexing (leverage TS work)
>> ·         Consolidation / feature cross population of KV,CS, and TS codebases
>> ·         Erlang / OTP upgrade
>> At this point we want to keep the structure of the day loose to allow the conversations to flow, our collective priorities to take precedence.
>> The sessions will be live streamed, with details to follow.
>> We will also man IRC / Slack for discourse.
>> Food and refreshments will be provided throughout the two days.
>> Hopefully this gives us something to discuss in the build up to the 12th Oct. We’re looking for everyone’s input so we can hit the ground running.
>> As a quick update on the status of the purchase. We have exchanged funds and the court process continues. One clarifying point for anyone following the court proceedings. The purchasing company is our technology arm, Hillside Technology Limited, not the bet365 group.
>> Thanks,
>> Andy.
