我似乎在 Druid 网站上找不到任何特定的教程/文档页面,其中列出了 Druid 中所有支持的维度数据类型。从我读了多少,我知道 long, floatstring绝对支持,但我对其他支持的类型的信息几乎为零。

对此的任何帮助将不胜感激,谢谢!

最佳答案

Druid natively supports five basic column types: "long" (64 bit signedint), "float" (32 bit float), "double" (64 bit float) "string" (UTF-8encoded strings), and "complex" (catch-all for more exotic data typeslike hyperUnique and approxHistogram columns). Timestamps (includingthe __time column) are stored as longs, with the value being thenumber of milliseconds since 1 January 1970 UTC.


我发现此页面包含支持的类型列表:
https://druid.apache.org/docs/latest/querying/sql.html#data-types
