【Teacher’s Day Appreciation】Thank You to the 196 Teachers Who Contributed 749 Technical Articles to Build the TiDB Column, with a Small Surprise Inside
In July 2019, the first community technical article was born: Using Gravity to Achieve Data Replication from MongoDB to TiDB. Since then, the TiDB community has had its own “technical article” section. With the improvement in the quantity and quality of content, the “column” was launched in February 2022. Thanks to everyone, a small “technical article” category has been built into a standalone “column.” From February 2022 to now, in more than half a year, the community’s evangelists have increased from 137 to 196! These 59 new forces in the community are also leading the community towards a better future together~

We hope that through this survey, TiDBers can provide some case-by-case documentation suggestions and work with the documentation team to polish the documentation, so that it can help more TiDBers handle and solve technical problems encountered in daily work.

Sometimes venting is to relax, to release pent-up anger, grievances, and hostility, which is more beneficial to physical and mental health.
