>                 Key: OAK-3807
>                 URL: https://issues.apache.org/jira/browse/OAK-3807
>             Project: Jackrabbit Oak
>          Issue Type: Technical task
>          Components: rdbmk
>    Affects Versions: 1.2.9, 1.0.25, 1.3.12
>            Reporter: Tomek Rękawek
>            Assignee: Julian Reschke
>             Fix For: 1.4
>
>
> There's the ORA-01795 error in Oracle. It's description is:
> {quote}
> ORA-01795 maximum number of expressions in a list is 1000 error
> {quote}
> We should review the RDBBlobStore and RDBDocumentStoreJDBC and split lists longer than 1000 elements to chunks.
> For instance, if the limit would be 3, then our lists can be split as follows:
> {code}
> ... XYZ in (?,?,?,?,?,?,?,?) // initial version
> ... (XYZ in (?,?,?) or XYZ in (?,?,?) or XYZ in (?,?)) // fixed version
> {code}
> In the patch for OAK-3637 there's {{RDBDocumentStoreJDBC#appendInCondition}} method that appends appropriate expression to the query. It should be used every time we have an {{in}} operator with variable number of placeholders.
