Changeset: a30054adfa29 for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB/rev/a30054adfa29
Modified Files:
gdk/gdk_bbp.c
Branch: Jun2023
Log Message:
If a bat is not in memory, it does not have to be saved.
This also prevents a possible deadlock from happening (BBPquickdesc
waits for BBPSYNCING status flag which is set at the time dirty_bat is
called).
