Aerospike Database

Compared to Redis and memcacheD, high availibity is best from Aerospike. Load balancing is also well done through Aerospike. If you're doing K/V lookups data exceeds more than 1MB, then Aerospike definitely fits the bill. However, it is not best as a document store. It is really atrocious in that nature. If anything look @ Mongo or something else then.

Riak

Riak is well suited as a key value store. It does exactly what it says it does. If you have well known buckets/keys, Riak is a great solution for a ton of different use cases. The lack of ability to search is somewhat problematic for other use cases requiring this ability.Also, while the ability to store a variable array of data into a single bucket/key is extremely useful, if you have a use case requiring parts of that value to be updated independently, Riak does not support transactions so you open yourself up to contention issues if the data is being updated regularly in small portions. One solution to this is to use multiple bucket/key parts to store the data, which will remove the contention issue, but then you have to increase your Riak footprint which results in more buckets and can sometimes make things more difficult than needed. This has been a nagging issue we've had to deal with on multiple occasions.

Pros

  • Scales really quickly and easily. Can deploy a new cluster or add to a cluster fairly quick.
  • MGMT UI is easy to use. Utilizing cli, makes it easy to "autoscale" for us.
  • The sharding removes any need to overlook to make sure if balanced correctly.
  • HA is dead simple, that almost little to no need figure out how to do it.

  • Riak is great at handling large volumes of requests. We've seen Riak perform well under large volume while keeping response times quite low.
  • Riak is also fast providing consistent sub 10ms reads in both the datacenter and cloud.
  • Flexible allowing storage of numerous data types. We heavily leverage this to store various JSON documents in a single bucket.
  • We really like the RESTful interface that is provided. Makes the learning curve almost invisible and provides a quick speed to market in using Riak.

Cons

  • Load balancing per network segments.
  • Reduction in price.
  • Cross datacenter replication usage isn't so straightforward. Sometimes cross dc replication can have issues of bad data..

  • Deletes!!! We've seen on numerous occasions where Riak has "resurrected" deleted data. We've worked with Basho numerous times and tried multiple changes to the way we interact with Riak to prevent the problem but it still remains. The deletes seem to reappear weeks, even months, after the delete was issued. We've had to work around this issue by providing a "deleted" flag for all data objects stored in Riak. Thus, we do no delete but simply flip the flag. Excess baggage we would really like to not have to worry about.
  • Search. Currently there's no way to tell what data you have in Riak without already knowing a particular bucket/key. There is a way to list the keys for a given bucket but due to performance implications, this is not a viable method to lookup data. Especially when you have a large amount of keys in the bucket.

If money isn't an issue, and you're not on the cloud, then I'd go with Aerospike. If you're the cloud ie, aws or azure, then i'd stick with dynamoDB or Cosmos then. Aerospike is definitely not something you want to put into the cloud. It doesn't work well w/ cross regions. If cross DC, you'll have to write some stuff for data integrity checks.

Riak works great for our use case but the fact that deletes seem to resurrect is a real issue for us. Unless we can get this solved, we'll continue to look at other products to see if our use case fits. Otherwise Riak is a great product and it fits our use case 95%. We have found work arounds to the remaining 5%.

Alternatives Considered

Compared to the above for K/V lookups and writes, it is faster. However, less than 1 MB, i'd use Redis, if you're willing to write package for HA in Redis. However HA between Redis and aerospike, aerospike is top notch. K/V lookups were 20-30% faster than Redis, 50% faster than Mongo, and 45% faster than Cassandra. But again, aerospike is really expensive.

Riak is a key/value pair store which is great for certain use cases. For our use case, the ability to search is an extremely useful feature. Apache Cassandra can provide this while Riak cannot. Also again for our use case, the ability to delete is critical as we strive to maintain clean data which means we like to purge old or obsolete data. Riak, while providing the ability to do so, is not reliable as we've seen data resurrect on numerous occasions. Apache Cassandra allows for deletes and in our proof of concept testing where we've explicitly tested this feature, it permanently deleted the data. One other key feature for us looking at Apache Cassandra is the ability to update multiple pieces of data simultaneously for a given row (Cassandra) or key (Riak). Riak only allows for updating at the key level by replacing the data that was there. Thus, if you have multiple threads updating the same data in Riak, contention issues arise and the possibility of overwriting data is a real concern. Apache Cassandra helps this use case by storing the data in columns rather than one big value. Thus, updating various columns for a given key removes contention issues in Cassandra.

Return on Investment

  • Less mgmt headaches, prompting time to focus on other issues.
  • HA, required little handholding. And minimization of downtime.
  • Cross region replication is not great, which sometimes requires data integrity checks on your end.

  • It provided a solution for use to securely write data to the cloud. This has been instrumental in allowing us to move more applications to the cloud. Writes are performed behind firewalls and then replicated to the cloud for application consumption. By moving more applications to the cloud, we free up internal resources and can serve information in a much more scalable and reliable way.
