Functions

func ConsistentHashFilter

func ConsistentHashFilter(name string, workers []string) (gtm.OpFilter, error)

returns an operation filter which uses a consistent hash to determine if the operation will be accepted for processing. can be used to distribute work. name: the name of the worker creating this filter. e.g. "Harry" workers: a slice of strings representing the available worker names

func ConsistentHashFilterFromDocument

func ConsistentHashFilterFromDocument(name string, document map[string]interface{}) (gtm.OpFilter, error)

returns an operation filter which uses a consistent hash to determine if the operation will be accepted for processing. can be used to distribute work. name: the name of the worker creating this filter. e.g. "Harry" document: a map with a string key 'workers' which has a corresponding

slice of string representing the available workers

func ConsistentHashFilterFromFile

func ConsistentHashFilterFromFile(name string, configFile string) (gtm.OpFilter, error)

returns an operation filter which uses a consistent hash to determine if the operation will be accepted for processing. can be used to distribute work. name: the name of the worker creating this filter. e.g. "Harry" configFile: a file path to a TOML document. the document should contain a property named 'Workers' which is a list of all the workers participating. e.g. workers = [ "Tom", "Dick", "Harry" ]
