Well, this is a fair point, that was discussed in the past, but to m= ake it short, Apache Cassandra is not dead or anything close. There is a = lot of activity. Some people are stepping out, other stepping in, and oth= er companies and individual are actively contributing to Cassandra. A ver= sion 4.0 of Cassandra is being actively worked on at the moment.

If there = are any other active participants in development=3F

Yes, directly or by open sourcing internal tools quite a few compani= es have contributed and continue&=23160;to contribute to the Apache Cassa= ndra ecosystem. I invite you to have a look directly at this de= v mailing list&=23160;and check people'= s email, profiles or companies. Check the Jira as well :).

Some people are working on Apache Cassandra for years and are around= to help regularly, they changed company but are still working on Cassand= ra, or even changed company to work more with Apache Cassandra in some ca= ses.

I'm also = interested which distribution is the most popular at the

I would say now you should start with C*3.0.last&=23160;or C* 3.11.l= ast. It seems to be the general consensus in the mailing list lately.
=46or Scylladb and Datastax I don't know about the version to&=23160= ;use. You should ask them directly.

Hi,

Recently Cassandra eco system became very fragmented:

Scylladb provides solution based on Cassandra wire protocol claiming
it is 10 times faster than Cassandra.

Datastax provides it's own solution called DSE claiming it is twice
= faster than Cassandra.
Also their site says =22DataStax no longer supports the DataStax
Community version of Apache Cassandra=E2=84=A2 or the DataStax Distributi= on of
Apache Cassandra=E2=84=A2.
Is their new software incompatible with Cassandra=3F
Since Datastax used to be the major participant to Cassandra
development and now it looks it goes on is own way, what is going to
be with the Apache Cassandra=3F
If there are any other active participants in development=3F

I'm also interested which distribution is the most popular at the
moment in production=3F

Best Regards,
Vitaliy
