Uber / concurrency-loadbalancerFile Age & Freshness

File age measurements show the distribution of file ages (days since the first commit) and the file freshness (days since the latest commit).

Summary

Number of files: 29
Daily file updates (only one update per file and date counted): 36
First update: 2020-08-22
Latest update: 2024-03-12
Days between first and latest update: 1,299 (185 weeks, estimated 925 working days)
Active days (at least one file change): 16
Files without commit history (ignored): 10 (210 lines of code)
