MesaTEE

MesaTEE is the next-gen solution to enable general computing service for security-critical scenarios. It will allow even the most sensitive data to be securely processed to enable offshore businesses without leakage.

MesaTEE has been incubating since 2019-08-19.

Three most important unfinished issues to address before graduating:

Finish the initial setup for MesaTEE and its sub-repos.
Choose a suitable name for MesaTEE and rename the repos.
Make the access control mechanism and RPC framework more scalable and ergonomic.

Are there any issues that the IPMC or ASF Board need to be aware of?

Regarding to the CI system, we do have some problem with migrating the webhooks. MesaTEE definitely requires CI runs on customized hardware. However, the Apache INFRA team is pretty conservative on adopting novel CI systems which support customized hardware and self-hosted agent, such as Github Action, Drone etc. We observed that Apache projects depending on CI running on customized hardware, such as incubator-tvm, experienced difficulty to migrate its webhooks and was challenged several times on the reason of using customized hardware in CI. Besides, we observed that Apache Spark is using Github Action, while we are blocked on it (see INFRA-19381).

The bootstrapping process seems slow due to the above problem. We have a temporary workaround to use our Drone CI system. It leverages a sync bot which automatically sync up incubator-mesatee and a testing fork and triggers the webook of the testing fork. For management, we force the developers to put the link of CI status for each PR in their PR message. It works, but we really desire the integration to new CI and self-hosted CI agents.

For the renaming, we found a new name "Teaclave" which is not used anywhere.

How has the community developed since the last report?

MesaTEE has one more contributor this month, and merged 50+ PRs from 13 contributors.

How has the project developed since the last report?

We implemented the new access control system in MesaPy, and merged into MesaTEE. The new access control system is much more powerful and flexible than traditional user/role/group based access control system, and is memory-safe and trusted with the help of MesaPy and MesaTEE.

We improved the MesaTEE infrastructure to make it k8s-friendly. We refactored parts of the MesaTEE system and are doing on others.

We improved the build system. We deprecated the old-fashioned Makefile, and only kept the cmake system.

We figured out a temporary solution for integrating the Drone CI system and self-hosted agents by syncing up incubator-mesatee and testing fork, and triggering tests on the testing fork.

We are improving the built-in RPC framework to use prost to automatically generate Rust source codes from protobuf's protocol definitions.

We fixed a couple of bugs reported from the open source community.

ShardingSphere

ShardingSphere is an ecosystem of transparent distributed database middleware, focusing on data sharding, distributed transaction and database orchestration.

ShardingSphere has been incubating since 2018-11-10.

Three most important unfinished issues to address before graduating:

Clear Brand issues with other ecosystem projects.
Further ASF culture and processes.
Make more apache releases.

Are there any issues that the IPMC or ASF Board need to be aware of?

No. Right now, the brand issues are under control, so we think board or IPMC may do not need do any actions for now.

There are still several related project on GitHub org in ShardingSphere ecosystem, before or during project joined the ASF incubator, such as extension modules, extension module examples and acceptance test are not in Apache repo. We have already moved some extension modules into into Apache repo, and plan to transfer all of them soon.

How has the community developed since the last report?

Ya Li, Zhiyi Yan have been voted and joined as committer.
There are 89 people to contribute codes to the main repo, there are 15 new contributors during last report. We are happy to see the community are growing up.
Over 100 companies have confirmed they are using ShardingSphere through issue report, and show at powered-by page[1]. Some companies has already provided patches to feedback the community.
Share a topic for Apache way and how to join ShardingSphere community in Apache meetup at Tsinghua University.
Finish Podling Maturity Assessment for ShardingSphere[2].
Plan to establish a co-meetup with Apache DolphinScheduler(incubator) in Beijing at Dec 8th.

[1]https://shardingsphere.apache.org/community/en/poweredby/ [2]https://cwiki.apache.org/confluence/display/SHARDINGSPHERE/Podling+Maturity+Assessment+for+ShardingSphere

How has the project developed since the last report?

Release 4.0.0-RC3 last month, main features are UI and SQL92 supported.
Accept donated sharding-scaling project and will merge to trunk before next release.
Plan to release 4.0.0 stable version soon.
