SingleStore aims to deliver the world’s fastest distributed SQL database for data-intensive applications: SingleStoreDB, which combines transactional + analytical workloads in a single platform.
Cost Effective & Flexible: Customers can start as low as a single OCPU VM up to 24 OCPUs. Customers pay only for OCPUs and Storage used.
Ease Of Getting Started: Customers can easily create Oracle Certified, full-featured, fully supported 11g, 12c (both 12.1 & 12.2) databases with choice of any database edition.
Built-in High Availability Constructs: Customers can easily deploy 2-node RAC configurations with all the VM shapes. For example: Easily deploy a 2-node RAC configuration with 2 core Virtual Machines and shared block storage of up to 40 TB.
Durable & Scalable Storage: Customers can use remote storage starting at 256GB up to 40 TB. Storage can be scale up with no downtime.
Secure: Customers still get all the advantages of our Oracle IAM for management control and VCN Security lists for securing their database environments.
Our workload is 100% analytical. We also have to ingest a lot of data each month. SingleStore is a perfect match for our needs because it has fast pipelines for data ingestion and great performance, even in large and complex queries. We need fast response times for our user interface and great performance in our ETL processes, which are rather complicated. SingleStore handles all of this very well.
When we restart the DBaaS instance, it seems like we had to add the NIC network back again. I'm not sure if it's specific to our instance configuration!
We wish the product had better support for High Availability of the aggregator. Currently the indexes generated by the two different aggregators are not in the same sequential space and so our apps have more burden to deal with HA.
More tools for debugging issues such as high memory usage would be good.
The price was the one that kept us away from purchasing for the first few years. Now we are able to afford due to a promotion that gives it at 25% of the list price. Not sure if we'll continue after the promotion offer expires in another 2 years.
[Until it is] supported on AWS ECS containers, I will reserve a higher rating for SingleStore. Right now it works well on EC2 and serves our current purpose, [but] would look forward to seeing SingleStore respond to our urge of feature in a shorter time period with high quality and security.
SingleSore can perform transactions and operational analytics together in order to utilize their data and transform their business. SingleStore delivers a database that performs both functions. Before using SingleStore, we had different systems for OLTP queries and for OLAP analyses, and a number of ETL packages to bring data from the OLTP system to Reporting database.
Very responsive to trouble tickets - Often, I think, the SingleStore's monitoring systems have already alerted the engineers by the time I get around to writing a ticket (about 10 - 20 mins after we see a problem). I feel like things are escalated nicely and SingleStore takes resolving trouble tickets seriously. Also SingleStore follows up after incidents to with a post mortem and actionable takaways to improve the product. Very satisfied here.
We allowed 2-3 months for a thorough evaluation. We saw pretty quickly that we were likely to pick SingleStore, so we ported some of our stored procedures to SingleStore in order to take a deeper look. Two SingleStore people worked closely with us to ensure that we did not have any blocking problems. It all went remarkably smoothly.
I would prefer the oracle database as service where my complete implementation is on Oracle Cloud Platform and as BI Implementation where datawarehouse is built on oracle database.
Vertica, Snowflake, SQL Server, Azure Data Warehouse, PowerBI, Aerospike, etc. From what I've seen MemSQL is well worth the cost when latency and data freshness needs are high, i.e. you need a lot of queries to run with UI latency (the query itself takes less than a second or so), with very fresh streaming fact and dimensional data. It will be more expensive per "unit of performance" but if you need that performance then it'll get the job done.
On-prem Vertica (note, not Eon) provides more knobs for optimizing a particular data set and set of queries against it and performs as well or better in a single table, fact table queries. It will also scale to data size more cheaply due to its on-disk model. For large queries against large data sets where data freshness isn't as important (and latency either is or isn't), I'd take Vertica, although if you need to do a lot of joins that will struggle). However, as they still are exclusively columnar, dimension table updates, and recalls based on them, can only be tuned to happen so fast (we could do much better than 10 seconds with 10-100 updates per second for raw replication, and Vertica's joins are always slow so recalls were worse).
Snowflake suffers similarly to Vertica in the data freshness, replication, and re-calc area; SF also doesn't give as many knobs to turn as Vertica for data set optimization but seems to be better at joins. If you have a lot of queries to run against a lot of data and joins are limited, you need query latency low and consistent but you don't need a ton of freshness, I'd stick with Vertica. If joins matter more, or you can accept notably-but-not-terribly worse performance, then Snowflake is fine and cheaper from what we've seen. (Again, I can't speak to SF vs Vertica Eon).
SQL Server and ADW we couldn't get to perform as well as the other options, but I'll say we didn't try that hard on those.
Aerospike is amazing as a KV store; however for OLAP use cases where you want to balance performance against the flexibility of queries against general event (time series) data (i.e. be able to roll up to different grains) then KV becomes challenging.
PBI is great if you want an integrated BI tool, but if you want an OLAP solution to build against, with some particular scale or performance needs to be mentioned above, I'd go with one of these other solutions. It really can be great for letting non-tech folks build relatively small data sets and quick insights for customers (internal or external), great leverage in that case.
Billing on Hosted Environment per hour, OCPU per hour, block volumes, object storage, etc.
Costing & maintenance, patching.
Security & TDE cycles.
Backups & recovery.
The features are complemented by database lifecycle management features, like configuration management, performance management, patch automation, etc. which make the solution complete from a DBaaS administrator’s perspective as well.
Manager 12c covers all the major use cases for DBaaS, which yield significant business benefits and high ROI.
As the overall performance and functionality were expanded, we are able to deliver our data much faster than before, which increases the demand for data.
Metadata is available in the platform by default, like metadata on the pipelines. Also, the information schema has lots of metadata, making it easy to load our assets to the data catalog.
