Hi, the netcdf4-python project (http://netcdf4-python.googlecode.com/svn/trunk/docs/netCDF4.Dataset-class.html#createVariable) supports a "least_significant_digit" attribute when creating a variable/array. This leads to a truncation of the array data before storing it to disk (https://code.google.com/p/netcdf4-python/source/browse/trunk/netCDF4_utils.py#26), which leads to be zlib compression more effective.
My question: Is the same true when I compress the array data with blosc? Will I get significant compression improvements when truncating my data before storing it in pytables? Thanks for your insight :) -- Andreas. ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
