com.alvazan.orm.api.base.NoSqlEntityManager.find()
This is NOSql so do NOT use find in a loop!!!! Use findAll instead and then loop over the items. If your network latency is 5 ms, looking up 1000 records will cost you 5 seconds in a loop(plus processing time) where findAll will cost you 5 ms (plus processing time). ie. findAll is better for looking up lots of entities!! @param entityType Entity for which keys need to be find @param key Rowkey of the Object @return The object of that Entity for which a rowkey is found
