Use of "precision_step" in elasticsearch mappings
elasticsearch, lucene
Solution
It is part of the mapping for dates and numbers.
It is a Lucene concept, you can read more here: Lucene doco
From the Lucene Doco:
Good values for precisionStep are depending on usage and data type:
The default for all data types is 4, which is used, when no precisionStep is given.
Ideal value in most cases for 64 bit data types (long, double) is 6 or 8.
Ideal value in most cases for 32 bit data types (int, float) is 4.
For low cardinality fields larger precision steps are good. If the cardinality is < 100, it is fair to use Integer.MAX_VALUE (see below).
Problem
In elastic search mapping there is an optional field called precision_step. What it means . I searched in google . i cant find any solid info about. Can anyone please explain what is a precision_step and use of it..! thanks in advance..!
