Class | Description |
---|---|
CompressionCharacterization |
This code is used both by unit tests, for short running tests,
and by the characterization repository for longer running, more exhaustive testing.
|
CpcSketch |
This is a unique-counting sketch that implements the
Compressed Probabilistic Counting (CPC, a.k.a FM85) algorithms developed by Kevin Lang in
his paper
Back to the Future: an Even More Nearly
Optimal Cardinality Estimation Algorithm.
|
CpcUnion |
The union (merge) operation for the CPC sketches.
|
CpcWrapper |
This provides a read-only view of a serialized image of a CpcSketch, which can be
on-heap or off-heap represented as a Memory object, or on-heap represented as a byte array.
|
MergingValidation |
This code is used both by unit tests, for short running tests,
and by the characterization repository for longer running, more exhaustive testing.
|
QuickMergingValidation |
This code is used both by unit tests, for short running tests,
and by the characterization repository for longer running, more exhaustive testing.
|
StreamingValidation |
This code is used both by unit tests, for short running tests,
and by the characterization repository for longer running, more exhaustive testing.
