> The current (new) algorithm (introduced in OAK-5855) may cause SELECT and
> DELETE statements to run concurrently, which might cause problems on certain
> DBs, such as SQL Server.
> Added a fallback (triggered by a system property) to the older (but slower)
> algorithm. Select it by setting system property like that:
> {noformat}
> -Dorg.apache.jackrabbit.oak.plugins.document.rdb.RDBVersionGCSupport.MODE=1
> {noformat}
