Hi all, Looking back into 2019, I wanted to take a moment and thank all these people who helped the project in one way or another. I know that stats do not always tell the truth but it is a concrete measure that shows the extraordinary effort of some people.
Doing some post-processing on the commit logs (of Calcite & Avatica master) between Jan 2019 and Jan 2020, here what the numbers say: *Reviewers of the year* Committer mail COUNTA of Review SUM of Lines modified jh...@apache.org 60 20652 h.y...@alibaba-inc.com 79 8531 yuzhao....@gmail.com 56 7004 mailto...@126.com 8 3736 zabe...@gmail.com 25 3465 michael.m...@gmail.com 16 3431 25229979+asereda...@users.noreply.github.com 25 3353 rube...@gmail.com 9 2293 hon...@apache.org 13 2026 jcama...@apache.org 13 1293 sitnikov.vladi...@gmail.com 20 1049 vvo...@gmail.com 2 899 lauren...@users.noreply.github.com 6 867 mm...@cs.rit.edu 4 675 chun...@apache.org 10 674 laur...@dremio.com 3 668 els...@apache.org 3 610 francischu...@apache.org 6 324 kris...@apache.org 4 318 k...@rxd.hu 2 101 An vital part of every project is reviews. The people above have dedicated a big part of their time reviewing and merging work of others. Looking into our backlog of PRs this is an area that we are a bit behind and we should try to do better next year. Of course there are a few individuals (Julian, Haisheng, Danny) who took on their shoulders a big burden and whom we should try to imitate within our capacity. I would like also to mention that there are many people (committers & non committers) who are helping a lot the project by reviewing PRs in GitHub. Unfortunately, I didn't find an easy way to extract such stats from GitHub to include them above. *Committers of the year* Author mail SUM of Lines modified COUNTA of Commit sitnikov.vladi...@gmail.com 83780 97 jh...@apache.org 36662 63 yuzhao....@gmail.com 22391 55 kht...@linkedin.com 7273 1 zabe...@gmail.com 7122 34 hon...@apache.org 5691 20 rube...@gmail.com 5475 30 chun...@apache.org 4341 27 x1q...@163.com 4210 15 jinxing.co...@gmail.com 3227 24 h.y...@alibaba-inc.com 3026 28 1989yanlinw...@163.com 2562 15 j.feina...@pragmaticminds.de 2426 2 wellfeng...@gmail.com 1932 16 jcama...@apache.org 1711 12 vg...@apache.org 1630 11 ihor.huzenko....@gmail.com 1545 5 25229979+asereda...@users.noreply.github.com 1388 21 francischu...@apache.org 1355 35 yanzhi....@antfin.com 1298 14 mouhoubi.kha...@gmail.com 1295 2 953396...@qq.com 1061 10 shuo...@alibaba-inc.com 1051 4 ming...@ebay.com 1047 1 laur...@apache.org 1009 10 k...@rxd.hu 989 15 j...@dremio.com 909 5 wuchong...@alibaba-inc.com 818 1 vvo...@gmail.com 769 5 riteshkapoor.opensou...@gmail.com 747 4 hhlai1...@gmail.com 727 1 siddha...@dremio.com 705 3 absolute...@qq.com 685 1 prav...@dremio.com 650 1 wenhui_t...@yeah.net 646 8 m.gelb...@gmail.com 577 3 kris...@apache.org 558 13 mm...@cs.rit.edu 545 17 st...@stoty.hu 532 1 ming.moria...@gmail.com 488 4 chunwei...@163.com 406 2 bohdan.kazy...@gmail.com 404 2 cyazb...@murex.com 347 1 xndai....@live.com 345 9 godfre...@163.com 321 3 shlok7...@github.com 320 1 ryan...@looker.com 320 3 lame...@users.noreply.github.com 316 4 chiboch...@gmail.com 299 1 zuoz...@gmail.com 279 1 yuzhao....@alibaba-inc.com 246 1 amaliu...@163.com 227 6 wmy7...@gmail.com 201 3 krishnakant.agra...@datametica.com 199 2 785294...@qq.com 193 1 dam6...@gmail.com 156 2 bot...@apache.org 154 2 snuyan...@gmail.com 139 3 nishant.mon...@gmail.com 129 1 chenghe...@gmail.com 124 1 weidong3...@126.com 120 2 wuchienc...@qq.com 118 2 b.hano...@criteo.com 116 1 justin.sw...@looker.com 104 1 whlwanghail...@didichuxing.com 103 1 asi...@maprtech.com 96 1 pengzhiwei2...@icloud.com 95 3 ste...@looker.com 94 2 stuti.gu...@datametica.com 92 1 mel...@murex.com 90 1 1269223...@qq.com 90 2 walter_...@hotmail.com 88 1 justin.szel...@gmail.com 88 3 hpe...@uber.com 88 1 mail.mondal.s...@gmail.com 85 1 doc...@gmail.com 79 2 beyond1...@126.com 77 1 490081...@qq.com 76 2 wellfeng...@tencent.com 73 1 zhaindr...@hortonworks.com 72 1 fudian...@alibaba-inc.com 62 1 bake....@alibaba-inc.com 59 1 shikha.som...@servicesource.com 57 1 laur...@dremio.com 53 1 seancx...@gmail.com 48 2 sahi...@spotify.com 47 1 9326...@gmail.com 37 1 –fengfeng_...@163.com 32 1 renhe....@antfin.com 31 1 els...@apache.org 31 6 zhuan...@dragonsoft.com.cn 29 1 divyansh...@datametica.com 29 1 wuyunfen...@baidu.com 28 1 hello...@gmail.com 28 1 pressenna.sockalingas...@omnisci.com 26 1 liusiyu...@360.cn 25 1 li.x...@kyligence.io 25 1 j...@apache.org 25 1 44845836+chad...@users.noreply.github.com 23 1 zj48...@ly.com 19 1 dijksp...@outlook.com 17 1 zhaofax...@kuaishou.com 15 1 gianmerl...@gmail.com 15 1 zuozhi....@alibaba-inc.com 14 1 quxiucheng 14 1 fo...@apache.org 14 7 yuling...@alipay.com 7 2 rayok...@gmail.com 6 1 m...@glimpse.io 6 2 donga...@outlook.com 6 1 liaoxia...@yunnex.com 5 1 wang...@163.com 4 1 ludo.a...@gmail.com 4 1 jinlan...@gmail.com 4 1 amaliu...@gmail.com 4 1 49699333+dependabot[bot]@users.noreply.github.com 4 2 shawn.c...@geminidata.com 2 1 mayozh...@tencent.com 2 1 lanny...@139.com 2 1 dai...@outlook.com 2 1 contextshuffl...@gmail.com 2 1 pa...@contiamo.com 1 1 Apart from reviews, code contributions is the other essential element of the project. Even a single line of code can have a big impact on the project so a big thanks to all these people above. Last but not least, I would like to thank all those people who participate in the discussions in the dev list that I enjoy so much reading. Bringing up ideas and helping each other is very important for the project and the community. Again this is something that cannot be measured easily and put into numbers but we all appreciate a lot. Best, Stamatis PS. Please excuse me, if somehow I screwed up some numbers
