前两天和一位同行聊起来：给传统的tp型数据库，增加列式数据处理能力，比如存取parquet数据、比如增加时序型数据的处理，好像还有点搞头。
有不少给postgresql增加了这些能力的项目了（例如pg_duckdb），我在想：也许也可以把这些做法照搬到sqlite上面。
另外，他也提到另一个观点：对于大部分企业来说，时序类+文本搜索类场景，应该覆盖了90%以上的AP需求了。

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.
Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
