ANALYSIS OF TIME OF TABLES CONNECTION IN NOSQL DATABASES AND ON MAPREDUCE TECHNOLOGY
This paper deals with problems of NoSQL databases replication. The model of database access for weak consistency case (W = R = 1) was developed. It was achieved the estimated probability that in the process of N replicas updating at least one request to read from old replicas will arrive. The analysis of the obtained results was provided.
Keywords: NoSQL database, consistency in the final analysis, strong consistency, Laplas-Stiltes transformation, generating function, access probability.
