Example 1 with DataMapModel

use of org.apache.carbondata.core.datamap.dev.DataMapModel in project carbondata by apache.

the class MinMaxIndexDataMapFactory method getDataMaps.

/**
 * getDataMaps Factory method Initializes the Min Max Data Map and returns.
 *
 * @param segment
 * @return
 * @throws IOException
 */
@Override
public List<CoarseGrainDataMap> getDataMaps(Segment segment) throws IOException {
    List<CoarseGrainDataMap> dataMapList = new ArrayList<>();
    // Form a dataMap of Type MinMaxIndexDataMap.
    MinMaxIndexDataMap dataMap = new MinMaxIndexDataMap();
    try {
        dataMap.init(new DataMapModel(CarbonTablePath.getSegmentPath(identifier.getTablePath(), segment.getSegmentNo())));
    } catch (MemoryException ex) {
        throw new IOException(ex);
