类名称:Store
方法名:getScanner

Store.getScanner介绍

[英]Return a scanner for both the memstore and the HStore files. Assumes we are not in a compaction.
[中]返回memstore和HStore文件的扫描程序。假设我们没有处于压缩状态。

代码示例

代码示例来源:origin: NGDATA/lilyproject

/**
 * Do a small get/scan against one store. This is required because store
 * has no actual methods of querying itself, and relies on StoreScanner.
 */
public static List<KeyValue> getFromStoreFile(Store store,
                       Get get) throws IOException {
  MultiVersionConsistencyControl.resetThreadReadPoint();
  Scan scan = new Scan(get);
  InternalScanner scanner = (InternalScanner) store.getScanner(scan,
      scan.getFamilyMap().get(store.getFamily().getName()));
  List<KeyValue> result = new ArrayList<KeyValue>();
  scanner.next(result);
  if (!result.isEmpty()) {
    // verify that we are on the row we want:
    KeyValue kv = result.get(0);
    if (!Bytes.equals(kv.getRow(), get.getRow())) {
      result.clear();
    }
  }
  scanner.close();
  return result;
}

代码示例来源:origin: co.cask.hbase/hbase

scan.getFamilyMap().entrySet()) {
Store store = stores.get(entry.getKey());
KeyValueScanner scanner = store.getScanner(scan, entry.getValue());
if (this.filter == null || !scan.doLoadColumnFamiliesOnDemand()
 || FilterBase.isFamilyEssential(this.filter, entry.getKey())) {

代码示例来源:origin: harbby/presto-connectors

KeyValueScanner scanner;
try {
 scanner = store.getScanner(scan, entry.getValue(), this.readPt);
} catch (FileNotFoundException e) {
 throw handleFileNotFound(e);
