在移动应用程序上使用Lokijs的大型数据库

Question

Recently I come across with lokijs and I am planning to use it for my hybrid mobile app developed using Ionic. From my understanding, it is an in-memory database that will executes very fast. So, my questions is, will it work great with big database (maybe around 10-50MB or even more)? Does working with big database using lokijs will dramatically slow down the app?

Answer 1

The only operation that may result in a dramatic slow down is the periodic save of the db, as at the moment LokiJS does not support incremental saves, so the whole db is serialized. Beware of size limits when working with IndexedDB or localStorage, if you need unlimited resources then an fs adapter like lokijs-cordova-fs-adapter will do the trick. Retrieval of documents even on large dbs, if properly indexed, should be still very fast.
