> The VisibilityLabelFilter will see and count the "delete cell" if the scan.isRaw() returns true, so the (put) cell will be skipped if it has lower version than "delete cell"
> The critical code is shown below:
> {code:title=VisibilityLabelFilter.java|borderStyle=solid}
> public ReturnCode filterKeyValue(Cell cell) throws IOException {
> if (curFamily.getBytes() == null
> || !(CellUtil.matchingFamily(cell, curFamily.getBytes(), curFamily.getOffset(),
> curFamily.getLength()))) {
> curFamily.set(cell.getFamilyArray(), cell.getFamilyOffset(), cell.getFamilyLength());
> // For this family, all the columns can have max of curFamilyMaxVersions versions. No need to
> // consider the older versions for visibility label check.
> // Ideally this should have been done at a lower layer by HBase (?)
> curFamilyMaxVersions = cfVsMaxVersions.get(curFamily);
> // Family is changed. Just unset curQualifier.
> curQualifier.unset();
> }
> if (curQualifier.getBytes() == null
> || !(CellUtil.matchingQualifier(cell, curQualifier.getBytes(), curQualifier.getOffset(),
> curQualifier.getLength()))) {
> curQualifier.set(cell.getQualifierArray(), cell.getQualifierOffset(),
> cell.getQualifierLength());
> curQualMetVersions = 0;
> }
> curQualMetVersions++;
> if (curQualMetVersions > curFamilyMaxVersions) {
> return ReturnCode.SKIP;
> }
> return this.expEvaluator.evaluate(cell) ? ReturnCode.INCLUDE : ReturnCode.SKIP;
> }
> {code}
