Kitematic aerospike config file software#
The software employs two sub-programs that are codenamed Defragmenter and Evictor. The clustering is done using heartbeats and Paxos based gossip protocol algorithm. The client cluster-aware layer is used to track the cluster configuration in the database, and manages client direct communications to all the nodes in the cluster. Since version 4.0 (2018), Aerospike Database can be configured both as Available and Partition-tolerant (AP) or Consistent and Partition-tolerant (CP) under the CAP theorem. This allows the database to remain operational even when an individual server node fails or is manually removed from the cluster. The distribution layer is responsible to replicate the data across nodes to ensure the durability and immediate consistency properties of the transaction. Īerospike provides single-record ACID transactions. In that case, data would be persisted to either SSD, NVMe, PMEM or traditional rotational media. Aerospike also provide the ability to be store the data fully in RAM thus acting as an in-memory database. This architecture to fetch all records from the persistent device and void the use of data cache. Reading the data is done using a direct access to the record position on disk using a direct pointer from the primary index, and data writes are optimized through large block writes to reduce latency. The data layer stores the data in solid-state drive, NVMe or Persistent memory. Īerospike uses hybrid memory architecture: the database indices are stored fully in main random-access memory, while the data is stored on a persistent device using the data layer. It operates in three layers: a data storage layer, a self-managed distribution layer, and a cluster-aware client layer.

Kitematic aerospike config file license#
On June 24, 2014, Aerospike was opensourced under the AGPL 3.0 license for the Aerospike database server and the Apache License Version 2.0 for its Aerospike client software development kit. In 2012, Aerospike acquired AlchemyDB, and integrated the two databases' functions, including the addition of a relational data management system. The name "Aerospike" is derived from the aerospike engine, a type of rocket nozzle that is able to maintain its output efficiency over a large range of altitudes, and is intended to refer to the software's ability to scale up. In August 2012, the company - which had been providing its database since 2010 - rebranded both the company and software name to Aerospike.
