Design:Selecting data sources for read query data sharding #3

Open piotrsobecki opened 10 years ago

piotrsobecki commented 10 years ago

NormalDistribution approach

  1. Calculating the mean and standard deviation of read query complexity (actually read query execution complexity)
  2. Selecting for distribution only queries of certain complexity threshold
  3. Selecting data sources for distribution which deal best with given complexity
