[jira] [Commented] (KAFKA-9667) Connect JSON serde strip trailing
zeros
[ https://issues.apache.org/jira/browse/KAFKA-9667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17052373#comment-17052373 ]

---------------------------------------
big-andy-coates commented on pull request #8230: KAFKA-9667: Connect JSON serde strip trailing zeros
URL: https://github.com/apache/kafka/pull/8230
This change turns on exact decimal processing in Jackson for decimals, meaning trailing zeros are maintained. This means a value of `1.2300` can be deserialized and re-serialized to JSON without any loss of information.

> The Connect Json serde was recently enhanced to support serializing decimals as standard JSON numbers, e.g. `1.23`. However, there is a bug in the implementation: it's stripping trailing zeros! `1.23` is _not_ the same as `1.230`. Trailing zeros should not be dropped when de(serializing) decimals.
