C-Blosc2 API#

This section contains the C-Blosc2 public API and the structures needed to use it. C-Blosc2 tries to be backward compatible with both the C-Blosc1 API and format. Furthermore, if you just use the C-Blosc1 API you are guaranteed to generate compressed data containers that can be read with a Blosc1 library.

Having said that, the C-Blosc2 API gives you much more functionality, like 64-bit data containers, more filters, more support for vector instructions, support for accelerated versions of some codecs in Intel’s IPP (like LZ4), the ability to work with data either in-memory or on-disk (frames) or attach metainfo to your datasets (metalayers).
