--------------------------
Component/s: (was: Query Execution)
Metadata Versioning
> Change data type for Metadata Versioning versions from int64 to uint64
> ----------------------------------------------------------------------
>
> Key: HAWQ-46
> URL: https://issues.apache.org/jira/browse/HAWQ-46
> Project: Apache HAWQ
> Issue Type: Improvement
> Components: Metadata Versioning
> Reporter: George Caragea
> Assignee: George Caragea
>
> Metadata versioning versions are uint64 currently. But at some point during
> version generation, we use an atomic operation that returns int64 and then
> cast it to unsigned:
> {code}
> uint64
> mdver_next_global_version()
> {
> return (uint64) gp_atomic_add_64(mdver_global_version_counter, 1);
> }
> {code}
> Change all places that handle versions to use unsigned 64 bit integer values.
