Aerospike key-value store (KVS) operations associate keys with a set of named values. On cluster startup, Aerospike configures policy containers—namespaces (RDBMS databases)—which control the retention and reliability requirements for a set of data. Namespaces are divided into sets (RDBMS tables) and records (RDBMS rows). Each record has a unique indexed key, and one or more bins (RDBMS columns) that contain the record values. Aerospike supports numerous data types used for bin values, as arguments, and as UDF return values. Aerospike allows value-based queries using secondary indexes, where string and integer bin values are indexed and searched using equality (string or numeric) or range (numeric) filters. User-Defined Functions (UDFs) extend the functionality and performance capabilities of the Aerospike Database engine. In Aerospike, the aggregations framework allows fast, flexible query operations. Similar to MapReduce systems, aggregation emits results in a highly parallel fashion. Aerospike supports large data types (LDTs) that allow individual record bins to efficiently store large collections of elements. In Aeropike, you can use list data types when dealing with a size-bound list residing in a single bin. List operations allow server manipulation (such as adding or removing an item) without having to read and replace the entire bin value. Aerospike supports Geospatial store, index, and query.

* Multi Table Types - Normal Table, Wide Table, Primitive Table * Multi Indexing - create index on the fly or let db create on auto mode as defined * Json data support and parser * Composite key support, index on composite keys * Nested index for json data * Operations on ResultSet - Add, Append, Intersect * Built in abstraction for RealTime data analysis * Native support for opaque, string, int, long data type (for both key and value) * Improved design for duplicate key index - more efficient and lot more performant * Pre allocated client buffer for most of the operations - efficient use of memory * Error message support to retrieve last error * Server is available in C++ for Linux * Client is in C++ for Linux and Windows * Embedded DB is in C++, C#, Java on Linux and Windows
