OPEN SOURCE LIBRARIES : APACHE SPARK OR DASK?
An open source library can be a great help in data management, scaling of huge
datas and allocation of workloads according to the demands of the programs. Two of
the most common source libraries to keep in mind while choosing a big data
processing capacity are ‘Apache Spark’ and ‘Dask’. Both have their pros and cons
and both have different sets of data acceptance.
So while Dask may work parallel with Python and focus on task scheduling, Spark
simultaneously focuses on Big Data Workloads. While none of them is bad over the
other, choosing a correct library is of great importance. Let’s now understand the key
differences between Apache Spark and Dask.
Apache Spark came out in the year 2010 and has been dominantly in use as an open
source library ever since. Dask however, came out in 2014, and has its dominance set
up in smaller programs it can directly link to.
But while Spark’s main target is the Traditional Intelligence Operations for
Businesses, Dask has a step in both, the Intelligence Operation in businesses, but
also Operations in Scientific situations.
When comparing according to size, the Dask is comparatively smaller and more
lightweight. But this also does mean that the Dask has less features than Spark. So
while Spark has its own ecosystem where it is developed to integrate itself with
different Apache projects, Dask relies on the Python Ecosystem to operate instead.
The major difference, and the one that impacts your choices the most is the
language that both the libraries work on. Apache Spark works on ‘Scala’, with
acceptance of a little bit of Python and R. Being based on Scala, it easily operates
with Java Virtual Machine too. Dask however, as said before, works on a Python
ecosystem and this understands ‘Python’ as a core. It does however, accept, C, C++,
LLVM or any other thing which can be linked to Python or its ecosystem.
When discussing the internal designs, Apache Spark definitely has a higher level of
in-built designing. The latter, Dask, lacks here in a sense that it has a lower level of
designing. But the algorithm acceptance is quite different in both. So while Spark
has a more intense design, it lacks the complex algorithm flows, and vice-versa, the
Dask can accept more sophisticated algorithms.
These are some of the major differences that make up Apache Spark and Dask.
While there are a lot of absolute differences, some similarities can bring to term the
features that both the libraries possess.
Both Spark and Dask have a capacity to scale to a thousand-node cluster from a
single node. Similarly, they can both read and write languages such as CSV, ORC,
JSON, etc. Similarly, they can both deploy on the same clusters too. So which one do
you think could be more apt and useful and which one do you not?
