Redis tech tip #1

In order to delete members from your Redis Geo-spatial collection, you can use ZREM (underneath the hood, the data is stored in a sorted set)

Add a few (Indian) cities

GEOADD IndianCities 28.6108127 77.2060241 NewDelhi

​GEOADD IndianCities 12.9715987 77.5945627 Bangalore

GEOADD IndianCities 13.0826802 80.2707184 Chennai

The weather in Chennai humid — not my kind.. let’s remove it

ZREM IndianCities Chennai

You can also delete the entire collection using DEL IndianCities (usual stuff…)

Cheers!
