Re: [DISCUSS] TinkerPop Golang Driver (coming soon!)
Hi all, As you are likely all aware, we are progressing quickly towards the end of the Gremlin Go driver. We decided to combine Milestone 6 and 7 since almost every single 'advanced' driver feature and configuration option was pulled into a previous milestone, making that milestone a near no-op. The final schedule for the Gremlin Go driver is below: - Milestone 1 - Basic Connectivity with String Traversals - Milestone 2 - ResultSet and Programmatic Traversals - Milestone 3 - TinkerPop Build Infrastructure Integration - Milestone 4 - GA Ready - Milestone 5 - Sessions, Strategies, Translator, Remote Transactions - Milestone 6 - Advanced Driver Features, Configuration Options, Performance, and Documentation With that in mind, I am happy to announce we have a pull request open for Milestone 5 now! Link: https://github.com/apache/tinkerpop/pull/1619 Any additional eyes on the pull request are appreciated. Cheers! -- *Lyndon Bauto* Team Lead Bit Quill Technologies Inc. lynd...@bitquilltech.com https://www.bitquilltech.com
[ANNOUNCE] Gremlin Go is now Available in Go Package Manager
NOTE: This is not for production use cases. This is a preview release. I am happy to announce that we now have an Apache TinkerPop Gremlin Go driver release available in the Go package manager. Please see https://pkg.go.dev/github.com/apache/tinkerpop/gremlin-go/v3/driver?tab=versions for the versions available. You can review the documentation for the v3 driver here: https://pkg.go.dev/github.com/apache/tinkerpop/gremlin-go/v3/driver If you have a go project, you can grab a specific release version with go get github.com/apache/tinkerpop/gremlin-go/v3@v3.6.1-rc2 or go get github.com/apache/tinkerpop/gremlin-go/v3@v3.5.4-rc2. -- *Lyndon Bauto* Team Lead Bit Quill Technologies Inc. lynd...@bitquilltech.com https://www.bitquilltech.com

Re: [DISCUSS] Draft ASF Board Report - April 2022
Thanks Florian.
It sucks, man. Really sucks. The Apache Board meddled in TinkerPop so as to
appease some voracious mob of anonymous Twitter fools. I contend that all would
have been averted had someone stood up and simply said:
"Comon guys. Yes, Marko is an odd fella with a twisted sense of humor, but you
are not going to use that against him (and thus, our project) to satiate
whatever you think you are going to gain by ruining his relationship with
TinkerPop. I suggest you drop this and move on with your life.”
They are grown adults succumbing to childish “racist Nazi”-talk. Either they
lack wisdom or they bask in the easy power they can wield by adopting the
psychology of our sad, depressed, dopamine addicted adolescents. In your lives,
I urge you to standup to this “cancel culture” scourge. Companies are being
drained of talent, people fear their colleagues, disillusionment and isolation
are the symptoms of those afraid to speak their mind. Your mind is all you have
and every thought that passes through it is valid, true, for it _exists_ and
that is all the reason you need to say: “I think, therefore I am right."
Take care y’all,
Marko.

AW: [DISCUSS] Draft ASF Board Report - April 2022
Here is the final report I submitted to the board. I changed the structure a
bit as I've used the ASF Board Report Wizard for this which already suggests
a structure for board reports. This tool by the way also mentioned that we
should not simply include statistics like activity on mailing lists, but
only interpretations of those stats ("the story behind the metrics") if we
want to talk about them.
Stephen also informed me about gremlin-rs which has a very basic version of
a GLV for Rust and I mentioned the Discord events we had as they were also
in the last quarter.

## Description:
Apache TinkerPop is a graph computing framework for both graph databases
(OLTP) and graph analytic systems (OLAP).
## Issues:
There are no issues requiring board attention.
## Membership Data:
Community changes, past quarter:
- No new PMC members. Last addition was Joshua Shinavier on 2021-06-01.
- Mike Personick was added as committer on 2022-03-17. He has already
contributed great improvements around core aspects of Gremlin.
Stephen Mallette has decided to leave the PMC to focus on other aspects of
his
career. His contributions as a PMC member will be missed.
## Project Activity:
TinkerPop just released 3.5.3 and 3.6.0. Version 3.5.3 is mostly a
maintenance
release. 3.6.0 represents a major release with breaking changes and a
variety
of new features [1], including support for regular expressions directly in
Gremlin and better support for commonly used upsert-like functionality. The
default logging implementation in the distributions of Gremlin Server and
Gremlin Console was also changed in 3.6.0 from log4j 1.2.x to logback due to
the vulnerability CVE-2019-17571 [2].
These releases are accompanied by the first pre-release versions of
gremlin-go, making Gremlin natively available in Go which has been the
mostly
requested programming language for which we did not offer a Gremlin Language
Variant (GLV)[3] yet by users over the last years. Notable about this new
GLV
is also that it has not been developed by a single contributor but by a
group
of contributors who collaborated on this, an effort that was mostly led by
committer Lyndon Bauto.
### Releases:
3.5.3 was released on 2022-04-04.
3.6.0 was released on 2022-04-04.
3.4.13 was released on 2022-01-10.
3.5.2 was released on 2022-04-04.
## Community Health:
As already mentioned in the last board report, we are seeing growing
activity
on our Discord server. We now had the first live events on Discord in the
last
quarter where Arthur Bigeard, developer of the Gremlin IDE G.V() [4],
performed
a live demonstration of G.V().
We've learned that gremlin-rs [5], which is a Gremlin Language Variant for
the
Rust programming language, recently added support for some advanced
capabilities normally reserved for TinkerPop's official drivers. It is
interesting to note this growth in the wider TinkerPop community, as Rust,
after Go, is probably the next most requested programming language for
official support.
