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。

The messaging service and social-media platform owes creditors roughly $700 million by the end of April, according to people briefed on the company’s plans and loan documents viewed by The Wall Street Journal. At the same time, Telegram Group Inc. must cover rising equipment and bandwidth expenses because of its rapid growth, despite going years without attempting to generate revenue.
A Telegram spokesman declined to comment on the bond issue or the amount of the debt the company has due. The spokesman said Telegram’s equipment and bandwidth costs are growing because it has consistently posted more than 40% year-to-year growth in users.
