What is an overkill tune?

Overkill LFX tuning is a performance recalibration of the engine and transmission computers. The benefits of an Overkill tune are straight forward: More power, more instantaneous, improved transmission performance, and proper support for your additional modifications.

Why Impala is faster than Hive?

Coming back to the actual question, Impala provides faster response as it uses MPP (massively parallel processing) unlike Hive which uses MapReduce under the hood, which involves some initial overheads (as Charles sir has specified).

While processing SQL-like queries, Impala does not write intermediate results on disk(like in Hive MapReduce); instead full SQL processing is done in memory, which makes it faster.

Why is Impala faster than spark?

How does Apache Impala work?

Impala uses the distributed filesystem HDFS as its primary data storage medium. Impala relies on the redundancy provided by HDFS to guard against hardware or network outages on individual nodes. Impala table data is physically represented as data files in HDFS, using familiar HDFS file formats and compression codecs.

Can we do update in Impala?

You can use Impala Update command to update an arbitrary number of rows in a Kudu table. This statement only works for Impala tables that use the Kudu storage engine.
