## Description https://issues.apache.org/jira/browse/IOTDB-1667 ## How to test Add a UT in DataRegionTest. Before this PR, syncDeleteDataFiles costs `101ms ~ 1121ms`. After this PR, syncDeleteDataFiles costs about `12ms`. ``` @Test public void testIoTDBTabletWriteAndDeleteDataRegion() throws QueryProcessException, IllegalPathException, WriteProcessException, TsFileProcessorException { String[] measurements = new String[2]; measurements[0] = "s0"; measurements[1] = "s1"; TSDataType[] dataTypes = new TSDataType[2]; dataTypes[0] = TSDataType.INT32; dataTypes[1] = TSDataType.INT64; MeasurementSchema[] measurementSchemas = new MeasurementSchema[2]; measurementSchemas[0] = new MeasurementSchema("s0", TSDataType.INT32, TSEncoding.PLAIN); measurementSchemas[1] = new MeasurementSchema("s1", TSDataType.INT64, TSEncoding.PLAIN); long[] times = new long[100]; Object[] columns = new Object[2]; columns[0] = new int[100]; columns[1] = new long[100]; for (int r = 0; r < 100; r++) { times[r] = r; ((int[]) columns[0])[r] = 1; ((long[]) columns[1])[r] = 1; } InsertTabletNode insertTabletNode1 = new InsertTabletNode( new QueryId("test_write").genPlanNodeId(), new PartialPath("root.vehicle.d0"), false, measurements, dataTypes, measurementSchemas, times, null, columns, times.length); dataRegion.insertTablet(insertTabletNode1); for (int r = 50; r < 149; r++) { times[r - 50] = r; ((int[]) columns[0])[r - 50] = 1; ((long[]) columns[1])[r - 50] = 1; } InsertTabletNode insertTabletNode2 = new InsertTabletNode( new QueryId("test_write").genPlanNodeId(), new PartialPath("root.vehicle.d0"), false, measurements, dataTypes, measurementSchemas, times, null, columns, times.length); dataRegion.insertTablet(insertTabletNode2); long start = System.nanoTime(); dataRegion.syncDeleteDataFiles(); System.out.println(System.nanoTime() - start); Assert.assertEquals(0, SystemInfo.getInstance().getTotalMemTableSize()); QueryDataSource queryDataSource = dataRegion.query( Collections.singletonList(new PartialPath(deviceId, measurementId)), deviceId, context, null, null); Assert.assertEquals(0, queryDataSource.getSeqResources().size()); Assert.assertEquals(0, queryDataSource.getUnseqResources().size()); } ``` -- This is an automated message from the Apache Git Service.
