The “faux reader” is used for testing pipelines. It does not read from a file or database, but generates synthetic data to feed into the pipeline.

## Example¶

{
"pipeline":[
{
"bounds":"([0,1000000],[0,1000000],[0,100])",
"num_points":"10000",
"mode":"random"
},
{
"type":"writers.text",
"filename":"outputfile.txt"
}
]
}


## Options¶

bounds
What spatial extent should points be generated within? Text string of the form “([xmin,xmax],[ymin,ymax],[zmin,zmax])”. [Default: unit cube]
num_points
How many synthetic points to generate before finishing? [Required]
mean_x|y|z
Mean value in the x, y, or z dimension respectively. (Normal mode only) [Default: 0]
stdev_x|y|z
Standard deviation in the x, y, or z dimension respectively. (Normal mode only) [Default: 1]
mode
How to generate synthetic points. One of “constant” (repeat single value), “random” (random values within bounds), “ramp” (steadily increasing values within the bounds), “uniform” (uniformly distributed within bounds), or “normal” (normal distribution with given mean and standard deviation). [Required]
