Description
For Spring Data MongoDB 5.0, we should deprecate MongoCustomConversions.BigDecimalRepresentation.STRING (not for removal) and switch the BigDecimal default to BigDecimalRepresentation.DECIMAL128 to indicate that Decimal128 is the preferred data type enabling range queries.
Storing big decimals as string is still a valid option, deprecation expresses that there are certain limitations and applications can use that option if they are aware of the implications.
