CrateDB In Detail

Crate.io makes CrateDB.For the purpose of receive
sensor data similar to IOT you will find CrateDB,
a quasi-RDBMS.
Creators of CrateDB may be have a little show for
realizing that the R part was required but are
playing catch-up with regard.
Austrian guys from Berlin discovered an outfit
called as Crate.io and it is being converted into
a San Franciso company.
There are 22 employees and 5 paying customers in
Crate.io.
There are large number of production users in
crate.io and it has clearly active custers and
overall product downloads.
An open source CrateDB in an essence has less
mature solution to MemSQL. The choice for MemSQL

There Are No Relational Story Starts In CrateDB
There are original values or objects in a column
and these objects are nested/hierarchical
structures that are common in the
NoSQL/internet-backend world. 
But when they are BlOBS they are different
(Binary Large Objects). 
For strict schemas manual definition on the
structured objects a syntax for navigating the
structure in WHERE clauses is required. 
For automatically inferring dynamic schemas it is
simple enough for more suitable
development/prototyping than for serious
production.

Highlights of Technical CrateDB Includes
JSON documents are stored from CrateDB records. 
Relational case purely has the glorified text
strings of the documents regarded. 
IT was found that BLOB Storage was somewhat
isolated from the rest. 
The sharing story of CrateDB initiates with
consistent hashing 
The convenient and the lenient nature have many
local shards. 
There is a possibility to change your shard
counts and the future inserts will be given into
the new shards set.
