[teiid-issues] [JBoss JIRA] (TEIID-5077) Couchbase strange behaviour for long numbers

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-5077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13469496#comment-13469496 ] 

Steven Hawkins commented on TEIID-5077:
---------------------------------------

What resolution are you comfortable with:

1. Just document the issue
2. Add an import option (or execution property) to only use "safe" numeric types - which could exclude biginteger, long, and bigdecimal.  As an execution property we'd also exclude those conversions from pushdown as well.

> There is a strange limitation for storing large numbers (e.g. modelled as long) in Couchbase.

> The same behaviour with value: 28341791043587382
> which is being stored and retreived as: 28341791043587384
> I feel we need to document this behaviour and provide hints how to overcome it. (Modelling of the column as string on Couchbase's side and defining a view).
