ActivityBucketingStateType (Complex Type)

Items

• bucket

  Flags: RAM,runtime

  Multiplicity: [0,-1]

  Current buckets of work. Some buckets might be present implicitly: if a bucket with sequence number of N is present, it is expected that all unlisted buckets with numbers lower than N are complete. In a similar way, if no free bucket is available and we are not at the end it is expected that some free buckets are yet to be created. Present only in buckets-holding tasks (coordinator or standalone).

• numberOfBuckets

  Flags: RAM,runtime

  Multiplicity: [0,1]

  How many buckets are there? This is an indicative information, e.g. to be used when estimating total progress. Present only in buckets-holding tasks.

• bucketsProcessingRole

  Flags: RAM,runtime,AVals:3

  Multiplicity: [0,1]

  Role of this task in the processing of the buckets: standalone executor, coordinator, or worker. (This is somewhat duplicate to TaskActivityStateType.role but has slightly different meaning, so we keep it here.)

• scavenging

  Flags: RAM,runtime

  Multiplicity: [0,1]

  Are we in the scavenging phase? Present only in buckets-holding tasks, relevant only in coordinator-workers scenarios.

• scavenger

  Flags: RAM,runtime

  Multiplicity: [0,1]

  Is this task a scavenger i.e. will it wait until the work is done, looking for buckets that could be reclaimed? Present only in worker tasks.

• workComplete

  Flags: RAM,runtime

  Multiplicity: [0,1]

  True if all the work is complete: there are no more buckets to be processed. Present only in buckets-holding tasks.
