The "FrontPage_PT-BR" page has been changed by RodrigoHjort. http://wiki.apache.org/cassandra/FrontPage_PT-BR -------------------------------------------------- New page: ## Please edit system and help pages ONLY in the moinmaster wiki! For more ## information, please see MoinMaster:MoinPagesEditorGroup. ##master-page:FrontPage #format wiki #language en #pragma section-numbers off = Cassandra Wiki = Cassandra é um armazém de dados estruturados do tipo chave-valor que é altamente escalável, futuramente consistente e distribuído. O Cassandra reune as tecnologias de sistemas distribuídos do [[http://s3.amazonaws.com/AllThingsDistributed/sosp/amazon-dynamo-sosp2007.pdf|Dynamo da Amazon]] e o modelo de dados do [[http://labs.google.com/papers/bigtable-osdi06.pdf|BigTable da Google]]. Tal como Dynamo, o Cassandra é [[http://www.allthingsdistributed.com/2008/12/eventually_consistent.html|futuramente consistente (''eventually consistent'')]]. E assim como !BigTable, o Cassandra fornece um modelo de dados baseado em famílias de colunas mais rico que nos típicos sistemas de chave/valor. Cassandra teve seu código fonte aberto pelo Facebook em 2008, onde havia sido projetado por Avinash Lakshman (um dos autores do Dynamo da Amazon) e Prashant Malik (engenheiro do Facebook). De qualquer forma, você pode pensar no Cassandra como um Dynamo 2.0 ou um casamento do Dynamo com o !BigTable. Cassandra roda em produção no Facebook, porém ainda está sob pesado desenvolvimento. == General Information == * [[http://cassandra.apache.org/|Official Cassandra Website]] (download, bug-tracking, mailing-lists, etc) * [[ArticlesAndPresentations|Articles and Presentations]] about Cassandra. * [[DataModel|A description of the Cassandra data model]] * [[CassandraLimitations|Cassandra Limitations]]: where Cassandra is not a good fit == Application developer and operator documentation == * [[GettingStarted|Getting Started]] * [[http://www.datastax.com/docs|Datastax's Cassandra documentation]] * [[ClientOptions|Client options: ways to access Cassandra]] -- interfaces for Ruby, Python, Scala and more * [[IntegrationPoints]] -- list of ways Cassandra is integrated with other projects/products * [[RunningCassandra|Running Cassandra]] * [[ArchitectureOverview|Architecture Overview]] * [[UseCases|Simple Use Cases and Solutions]] -- please help complete * [[FAQ]] * [[Counters]] * [[SecondaryIndexes]] == Advanced Setup and Tuning == * [[StorageConfiguration|Storage Configuration]] * [[MultinodeCluster|Creating a multi-node cluster]] * [[Operations]] * [[Embedding]] * [[MemtableThresholds|Memtable Thresholds]] and other [[PerformanceTuning|Performance Tuning]] * [[CassandraHardware|Cassandra Hardware]] * [[CloudConfig|Configuration on Rackspace or Amazon Web Services]] * [[LargeDataSetConsiderations|Large data set considerations]] == Client library developer information == * [[API|Thrift API Documentation]] (In progress) == Cassandra developer Documentation == * [[HowToBuild|How To Build]] * ArchitectureInternals * [[CLI Design]] * [[HowToContribute|How To Contribute?]] * [[HowToCommit|How To Commit?]] * [[HowToPublishReleases|How To Release]] (Note: currently a work in progress) (Note: only relevant to Cassandra Committers) == Mailing lists == * Users: [email protected] [[mailto:[email protected]|(subscribe)]] [[http://www.mail-archive.com/[email protected]/|(archives)]] [[http://www.mail-archive.com/[email protected]/|(incubator archives)]] * Developers: [email protected] [[mailto:[email protected]|(subscribe)]] [[http://www.mail-archive.com/[email protected]/|(archives)]] [[http://www.mail-archive.com/[email protected]/|(incubator archives)]] * Commits: [email protected] [[mailto:[email protected]|(subscribe)]] == Related Information == * [[http://incubator.apache.org/thrift|Thrift]], used by Cassandra for client access * RelatedProjects: Projects using or extending Cassandra == Google SoC 2010 Page == * [[GoogleSoc2010|Google SoC]] This wiki is powered by MoinMoin.
