I've compiled a short summary of Substrait activity over the past three months (Jan 1 - Present, 2023). I plan on doing this roughly every quarter so that we can see levels of engagement, trends, etc. These numbers probably won't be extremely useful until we have collected them more regularly.
# Headline Statistics
In this interval there have been 83 commits and 1,037 comments (in both issues and PRs).
63 of these commits and 448 of these comments were from non-committers
During the previous 3 month period there were 65 commits.
# Distribution of Activity
The active repos are substrait, substrait-java, substrait-go, substrait-cpp, and substrait-rs
Most of the activity appears to be around building up initial support libraries for the various languages.
Although I don't have statistics for this (we don't have organizational information for non-committers) I do believe that most of the activity is coming from Voltron Data or Intel. It would be nice to diversify this.
# Rising Stars
The following were the most active non-committers during this period. These raw numbers need to be taken into context with less tangible factors (and not all commits or comments are equal) but they are good information when considering new committers:
