如何增加映射器配额？
我正在使用 Google App Engine Mapper API 删除 GAE 数据存储中特定实体的所有行（大约 2M）。然而，即使我有一个计费帐户，我仍然得到 -
com.google.appengine.tools.mapreduce.MapReduceServlet processMapper： 超出映射器配额。中止请求，直到配额得到补充。 考虑增加mapreduce.mapper.inputprocessingrate（默认 1000）如果您希望您的映射器工作更快地完成。
具体如何增加映射器配额？我需要紧急删除记录，但找不到任何文档来增加映射器配额。如果我应该知道任何其他最佳实践，请告诉我。
这就是我在映射器类中所做的。
public void map(Key key, Entity value, Context context) {
log.info("Mapping key: " + key);
if (value.hasProperty("email")) {
String email = (String) value.getProperty("email");
if(email.equalsIgnoreCase("[email protected]")) {
DatastoreMutationPool mutationPool = this.getAppEngineContext(context).getMutationPool();
mutationPool.delete(key);
}
}
I am using Google App engine Mapper API to delete all rows (approx. 2M) for a particular entity in my GAE datastore. However, even though I have a billed account, I still get -
com.google.appengine.tools.mapreduce.MapReduceServlet processMapper:
Out of mapper quota. Aborting request until quota is replenished.
Consider increasing mapreduce.mapper.inputprocessingrate (default
1000) if you would like your mapper job to complete faster.
How do I specifically increase the mapper quota? I need to remove the records urgently, but cannot find any documentation to increase mapper quota. If there is any other best practices I should be aware of, please let me know.
This is what I am doing in the mapper class.
public void map(Key key, Entity value, Context context) {
log.info("Mapping key: " + key);
if (value.hasProperty("email")) {
String email = (String) value.getProperty("email");
if(email.equalsIgnoreCase("[email protected]")) {
DatastoreMutationPool mutationPool = this.getAppEngineContext(context).getMutationPool();
mutationPool.delete(key);
}
}
