Mailing List Participation
The following plot (courtesy of Gmane), shows the steadily increasing post rate for cassandra-user
during 2009. Note: There are two mailing lists (-user
and -dev
), but most traffic goes to -user
regardless of topic.
Code Contributions
This plot shows the estimated number of unique contributors on a week-by-week basis.
Similar to the plot above, this shows unique contributors, but broken down by month instead of week.
