Hi, I am from the Azure Cosmos DB engineering team. All five consistency levels (strong, bounded staleness, session, consistent prefix, and eventual) are available for your Cosmos account, regardless of the number of…
Hi, I am from Azure Cosmos DB Engineering Team. The article is referring to the implementation details of automatic failover mechanisms inside of Cosmos DB service. For the customers, automatic failover is available as…
Cosmos DB codebase consists of multi-million lines of C++ code. It is fully asynchronous and like all large scale (stateful) distributed systems, it is also extremely complex. The database engine of Cosmos DB (including…
Read only transactions existed in DocumentDB too. DocumentDB was a strict subset of the capabilities that Cosmos DB provides/existed underneath. Hence, read only transactions exist in Cosmos DB too. The first technical…
For supporting the "oops I accidentally deleted my table/collection/graph - how do I get it back?" scenario, Cosmos DB automatically takes periodic, full backups of all your data. Currently, we restore your backups on…
Azure Cosmos DB is not related to the work on Corfu/CorfuDB.
Cosmos DB has native extensibility to support various APIs Azure Table Storage "APIs" is one of them. If you are a Azure Table Storage customers, by virtue of accessing Cosmos DB using the Table Storage API, you can now…
As the Cosmos DB SLA doc describes, for any of the 5 consistency models the service supports, the service guarantees all the other three guarantees (latency at the 99th percentile, availability and throughput) at…
Cosmos DB does local persistence and replication both within a region and across any number of regions.All data is durable and made highly available via replication. You dont need to take backups or restore them for…
There are many significant differences in capabilities, and design approaches between other systems and Cosmos DB. At a very high level. differences are at two levels - the design of the database engine and the larger…
Azure Cosmos DB has been many years in the making. Azure Cosmos DB started as “Project Florence” in late 2010 to address developer the pain-points faced by large scale applications inside Microsoft. Observing that the…
