Busca por Similaridade no CassandraDB

Abstract

A necessidade de escalabilidade em cenários de Big Data levou à prosperação dos NOSQL distribuídos. Contudo, as soluções mais amplamente usadas não suportam uma outra característica desejável, busca por similaridade. Neste artigo propomos contornar tal limitação estendendo o Cassandra com suporte a buscas por dados similares. Nossa abordagem usa hashing sensível à localidade para distribuir dados entre nós, direcionar buscas, e recuperar dados em armazenamento estável de forma eficiente. Descrevemos aqui como implementar esta abordagem, nosso plano de testes e resultados iniciais.
