Get.setTimeRange介绍

[英]Get versions of columns only within the specified timestamp range, [minStamp, maxStamp).
[中]仅获取指定时间戳范围内的列版本，[minStamp，maxStamp）。

代码示例

public static CompletableFuture<Optional<TableState>> getTableState(AsyncTable<?> metaTable,
  TableName tableName) {
 CompletableFuture<Optional<TableState>> future = new CompletableFuture<>();
 Get get = new Get(tableName.getName()).addColumn(getTableFamily(), getStateColumn());
 long time = EnvironmentEdgeManager.currentTime();
 try {
  get.setTimeRange(0, time);
  metaTable.get(get).whenComplete((result, error) -> {
   if (error != null) {
    future.completeExceptionally(error);
    return;
   }
   try {
    future.complete(getTableState(result));
   } catch (IOException e) {
    future.completeExceptionally(e);
   }
  });
 } catch (IOException ioe) {
  future.completeExceptionally(ioe);
 }
 return future;
}
