* Adds ddsketch_calc.py which implements a class for DDSketch related calculations
* Adds ddsketch_conversion.py for quickly computing a bucket index to a value or vice-versa
* Adds ddsketch_compare.py to compute how similar two ddsketch distributions are
* Adds export_graph.py to graph the ddsketch distribution outputted from mako
The arguments for ddsketch_conversion.py are:
-b, --bucket: the bucket index that we need to calculate the value from (optional)
-v, --value: the value that we need to calculate the bucket index from (optional)
-e, --error_guarantee: the error guarantee for ddsketch (optional, default is 0.005)
The arguments for ddsketch_compare.py are:
--file1: Path to first ddsketch json
--file2: Path to second ddsketch json
--txn1: The transaction type for the first file
--txn2: The transaction type for the second file
--op: The operation name (ex: GRV, GET ...)
The arguments for export_graph.py:
--file: path to ddsketch distribution
--txn, -t: Transaction type from file
--title: title for graph (optional, otherwise "Title" is used)
--savefig: Path to save the image plot (optional)
--op: Which operation to plot
