To maintain a consistent view of data, users can create a temporary snapshot. Data can be used for forward and backward iteration. Snappy is used to automatically compress data. External activity (file system operations, etc.) The information is transmitted via a virtual interface to allow users to customize the operating system interactions. A database with over a million entries is used. Each entry is assigned a 16-byte key and a 100-byte value. The benchmark reduces the size of the values to approximately half of their original size. The benchmark lists the performance of sequential reading in the forward and reverse directions, as well as the performance of random lookups.

JaguarDB allows for fast ingestion of time-series data and location-based data. It can also index in both time and space. It is also quick to back-fill time series data (inserting large amounts of data in the past time). Time series are usually a sequence of data points that have been indexed in order of time. JaguarDB uses the term time series to mean both a sequence data points and a set of tick tables that hold aggregated data values over a specified time span. JaguarDB's time series tables can contain a base table that stores data points in time order and tick tables such daily, weekly, monthly, and daily tables to store aggregated information within these time periods. The RETENTION format is identical to the TICK format, but it can have any number or retention periods. The RETENTION indicates how long data points in the base tables should be kept.

Presto is an open-source distributed SQL query engine that allows interactive analytic queries against any data source, from gigabytes up to petabytes.

Voldemort does not have a relational database. It doesn't attempt to satisfy arbitrary relationships while also satisfying ACID properties. It is not an object database that attempts transparently to map object reference graphs. Nor does it introduce a new abstraction such as document-orientation. It is essentially a large, distributed, persistent, fault-tolerant, hash table. This will allow applications to use O/R maps like active-record and hibernate, which will provide horizontal scaling and greater availability, but with a great loss in convenience. A system may consist of many functionally partitioned APIs or services that can manage storage resources across multiple data centres using storage systems that may be themselves horizontally partitioned. This is useful for large applications that are subject to internet-type scalability. Because all data is not in one database, it is impossible to make arbitrary in-database connections for applications in this space.
