I have an oracle table where most of the number fields are BigDecimal. I
want to migrate all the data from the table to elasticsearch. If I don't
provide any mapping, elasticsearch is taking the bigdecimal values as
double and the precision is lost. I was wondering if elasticsearch
provides the support for BigDecimal field type. My understanding is that it
now , as a workaround, I have used an explicit mapping where I mapped all
the BigDecimal fields to String. My question is how do I efficiently index
these bigdecimal fields, because I believe that using a string for
bigdecimal has performance issues.
