本期节目找来 Nebula 研发小哥,来聊下开源分布式图数据库 Nebula Graph v2.6 新功能 GEO (Geography Spatial)是如何做出来的, 可以在什么场景下去使用。

00:00 Intro

00:32 Geo Spatial 简介

01:12 Geo Spatial 的作用、场景简介

02:55 Geo 属性详解

05:55 在不支持 Geo 之前,用户是怎么在 Nebula 里满足地理信息相关需求的呢?

07:15 具体的例子:打车软件(涉及到空间索引,空间填充曲线,Google S2)

26:20 实现、设计功能过程中的点滴(数据类型选择的 tradeoff,空间索引算法选择)

34:55 使用 Geo Spatial 时候的注意事项

40:10 推荐的 Geo Spatial 方面参考资料

41:20 研发小哥工作日的一天

42:57 会支持 GeoJSON 的转入转出函数么?

44:52 Outro
