- "Maybe we could abstract slighty our use of jackson (put the helpers we need in Json.java maybe?), so that 1) we have only one place to change if we upgrade jackson and the API change (or we want to change of library) and 2) we save creating multiple ObjectMapper or JsonStringEncoder objects."

Subject: ScyllaDBKeong,
I saw your post on the Cassandra mailing list.
ScyllaDB is an open source drop-in replacement for Apache Cassandra. You can easily substitute Scylla for Cassandra in JanusGraph - in fact IBM has publicly spoken about why they chose Scylla instead of Cassandra for their JanusGraph as a Service. https://www.scylladb.com/tech-talk/performance-evaluation-scylla-database-backend-janusgraph-scylla-summit-2017/
And, because ScyllaDB is written in C++, there are no Jackson dependencies. So you'll be able to satisfy your security concerns, and take advantage of the fact that Scylla is faster and easier to manage.
We believe that there are already users of ScyllaDB within Huawei. For example, in March of 2018, our CEO and CTO met with Huawei Cloud, who are interested in offering Scylla as a Service. That potential partnership is still under discussion.
If you are interested in learning more, I would recommend dowloading the software at https://www.scylladb.com/download/, and joining our ScyllaDB Users Slack, where there are many Scylla users and engineers who can answer questions. http://slack.scylladb.com. (There is even a Chinese-language channel - #general-cn - on the Slack, if you prefer that to the mostly-English #general channel)
Good luck, and I hope to see you on the Slack!!!
Greg

Subject: Re: ScyllaDBSounds great!
I know that time is very short, but we are holding the Scylla Summit in 4 weeks - 6th November and 7th November. We will be near San Francisco. http://www.scylladb.com/scylla-summit-2018/ We welcome you and your team to attend the Summit, in order to better understand the technology and integrate with the user community.
There is also a full day of training on 5th November that would likely be valuable.
If it is possible for you and your team to come, I will be happy to waive the $500 fee for Training and Summit. Let me know, and I can arrange for the free registration. If necessary, I can also get you a letter of invitation, which may help with obtaining a visa.
