Can machine learning-based data structures i.e. learned data structures replace traditional data structures? This is a question recently asked and explored by a team of Google researchers led by Jeff Dean with a major focus on database indexes. p = F(Key) ? Learned Bloom filters.

ETL refers to extract, transform, load and it is generally used for data warehousing and data integration. There are several emerging data trends that will define the future of ETL in 2018. A common theme across all these trends is to remove the complexity by simplifying data management as a whole.

An inte ger in Python consumes 24 bytes instead of 4 bytes (because every object carries around type information, reference counts, and more), while the overhead for data structures like lists or dictionaries can be 4x that of their C++ counterparts. Are caches large enough for this code? Consider Python. . As Leiserson et al.

An example of a specification is the correct operation of the hardware of a microprocessor. If the fault is read but goes undetected, the outcome could be Silent Data Corruption (SDC). An SDC is the worst possible outcome of a fault, as it can have an arbitrary impact on the correctness of software running on the hardware.
