Compression¶

vortex.compress(array)¶

Attempt to compress a vortex array.

Examples

Compress a very sparse array of integers:

>>> import vortex as vx
>>> a = vx.array([42 for _ in range(1000)])
>>> str(vx.compress(a))
'vortex.constant(i64, len=1000)'

Compress an array of increasing integers:

>>> a = vx.array(list(range(1000)))
>>> str(vx.compress(a))
'fastlanes.bitpacked(i64, len=1000)'

Compress an array of increasing floating-point numbers and a few nulls:

>>> a = vx.array([
...     float(x) if x % 20 != 0 else None
...     for x in range(1000)
... ])
>>> str(vx.compress(a))
'vortex.alp(f64?, len=1000)'
