# InfluxDB design insights and tradeoffs

InfluxDB is a time series database. Optimizing for this use case entails some tradeoffs, primarily to increase performance at the cost of functionality. Below is a list of some of those design insights that lead to tradeoffs:

1. For the time series use case, we assume that if the same data is sent multiple times, it is the exact same data that a client just sent several times.
    
    ***Pro:*** Simplified [conflict resolution](/enterprise_influxdb/v1/troubleshooting/frequently-asked-questions/#how-does-influxdb-handle-duplicate-points) increases write performance.  
    ***Con:*** Cannot store duplicate data; may overwrite data in rare circumstances.
    
2. Deletes are a rare occurrence. When they do occur it is almost always against large ranges of old data that are cold for writes.
    
    ***Pro:*** Restricting access to deletes allows for increased query and write performance.  
    ***Con:*** Delete functionality is significantly restricted.
    
3. Updates to existing data are a rare occurrence and contentious updates never happen. Time series data is predominantly new data that is never updated.
    
    ***Pro:*** Restricting access to updates allows for increased query and write performance.  
    ***Con:*** Update functionality is significantly restricted.
    
4. The vast majority of writes are for data with very recent timestamps and the data is added in time ascending order.
    
    ***Pro:*** Adding data in time ascending order is significantly more performant.  
    ***Con:*** Writing points with random times or with time not in ascending order is significantly less performant.
    
5. Scale is critical. The database must be able to handle a *high* volume of reads and writes.
    
    ***Pro:*** The database can handle a *high* volume of reads and writes.  
    ***Con:*** The InfluxDB development team was forced to make tradeoffs to increase performance.
    
6. Being able to write and query the data is more important than having a strongly consistent view.
    
    ***Pro:*** Writing and querying the database can be done by multiple clients and at high loads.  
    ***Con:*** Query returns may not include the most recent points if database is under heavy load.
    
7. Many time [series](/enterprise_influxdb/v1/concepts/glossary/#series) are ephemeral. There are often time series that appear only for a few hours and then go away, e.g. a new host that gets started and reports for a while and then gets shut down.
    
    ***Pro:*** InfluxDB is good at managing discontinuous data.  
    ***Con:*** Schema-less design means that some database functions are not supported e.g. there are no cross table joins.
    
8. No one point is too important.
    
    ***Pro:*** InfluxDB has very powerful tools to deal with aggregate data and large data sets.  
    ***Con:*** Points don’t have IDs in the traditional sense, they are differentiated by timestamp and series.
