Examples of cloneWithNewSummarySamplingLevel()

org.apache.cassandra.io.sstable.format.SSTableReader.cloneWithNewSummarySamplingLevel()

Returns a new SSTableReader with the same properties as this SSTableReader except that a new IndexSummary will be built at the target samplingLevel. This (original) SSTableReader instance will be marked as replaced, have its DeletingTask removed, and have its periodic read-meter sync task cancelled. @param samplingLevel the desired sampling level for the index summary on the new SSTableReader @return a new SSTableReader @throws IOException

        SSTableReader original = sstables.get(0);


        SSTableReader sstable = original;
        for (int samplingLevel = 1; samplingLevel < BASE_SAMPLING_LEVEL; samplingLevel++)
        {
            sstable = sstable.cloneWithNewSummarySamplingLevel(cfs, samplingLevel);
            assertEquals(samplingLevel, sstable.getIndexSummarySamplingLevel());
            int expectedSize = (numRows * samplingLevel) / (sstable.metadata.getMinIndexInterval() * BASE_SAMPLING_LEVEL);
            assertEquals(expectedSize, sstable.getIndexSummarySize(), 1);
        }
