||
| ## 總結 | ||
|
|
||
| 原本是 10/16 就會結束的鐵人賽 <br> | ||
| 其實到今天 ( 12/06 ) 才正式寫完 TAT <br> | ||
|
|
||
| <br> | ||
|
|
||
| 在開賽前，我其實只有囤不到 10 篇的文章 <br> | ||
| 接下來都是盡可能一天生一篇 <br> | ||
| > 但是每篇包含 code 大概都落在 3000~5000 字 <br> | ||
| > 還有在新功能實作時，多少會遇到一些 bugs <br> | ||
| > 後期的文章都只能拿以前的文章先貼上去 <br> | ||
| <br> | ||
|
|
||
| 還有在最後 5 篇文章時，想不太到也寫什麼 ( 之前規劃的內容都寫完了 ) <br> | ||
| 也花了快一兩週來看其他文章、學新技術、找主題 <br> | ||
|
|
||
| <br> | ||
|
|
||
| 在實作也遇到蠻多出乎意料的問題 <br> | ||
| - 在處理 async genrator 時：發現需要透過 `asynccontextmanager` 才能正確的 yield 出 `AsyncSession` | ||
| - 以 Redis 實作 Pagenaion Cache 時：發現後端再處理資料合併時效率太低，用其他寫法才達到預期的效果 | ||
| - 實作 Primary Replica 架構時：發現以 `random.choice` 來選擇 Replica 會倒致效率低落，改用以 bitwise 實現 `round-robin` 才達到預期的效果 | ||
|
|
||
| <br> | ||
|
|
||
| 像是在處理 Pagenaion Cache 和 Primary Replica 架構問題時 <br> | ||
| 都分別花 3 天到 1 週才通靈出關鍵點 <br> | ||
|
|
||
|
|
||
| <br> | ||
|
|
||
| 在這兩個月的時間 <br> | ||
| 除了正式完成 iThome 鐵人賽 <br> | ||
| 也在 10 月打 [**NCPC 決賽**](https://ncpc.ntnu.edu.tw/)、[**ICPC 桃園站**](https://icpc.global/regionals/finder/Taipei) 和 [**ITSA 決賽**](https://www.itsa.org.tw/itsacontest/2023/register/index.php) <br> | ||
| 11 月 在 [**MOPCON 講議程**](https://mopcon.org/2023/schedule/)、參加 [**臺北程式節黑客松**](https://codefest.taipei/) 和 **聽 Coldplay演唱會** <br> | ||
| 是個非常充實的兩個月！<br> | ||
