List<T> docs = GetDocsFromDb(...) I need to keep the same order in both collections, so that the items in List<T> must be in the same position than in the first one (due to search engine scoring reasons). And this process cannot be done in the GetDocsFromDb() function. If necessary, it's possible to change the second list into some other structure (

For example let's say I have a query: SELECT * FROM SomeTable WHERE id IN (commaSeparatedListOfIDs) The commaSeparatedListOfIDs is being passed in from business logic and it can be any type of IEnumerable(of Integer) . How would I construct a query in this case? Do I have to do what I've been doing so far which is basically string concatenation or is there some sort of advanced parameter mapping

How to create auto increment IDs in Cassandra

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: We know that it is easy to create auto increment IDs in SQL databases, is there a good solution for it in Cassandra? The IDs should be for key or column name. 回答1: Creating a global sequential sequence of number does not really make any sense in a distributed system. Use UUIDs . (Because you would have to make all participants agree and accept the evolution of the sequence -- under a naive implementation) 回答2: How about the following, using Cassandra's Lightweight transactions 1 - Create IDs table: CREATE TABLE ids ( id_name varchar, next_id

I don't want to use toPandas() function given the drawback associated with it. Any help is appreciated. 回答1: If both dataframes are big, you should consider using an inner join which will work as a filter: First let's create a dataframe containing the

For ConsumerGroup I use ZooKeeper-based config and am completely satisfied with it, but SimpleConsumer requires seed brokers to be instantiated. I don't want to keep list of both - ZooKeeper and broker hosts. Thus, I'm looking for a way to automatically discover brokers for a particular topic from ZooKeeper . Because of some indirect information I belief that these data is stored

Is this an expected behavior or a bug ? Does anyone know a workaround to make nvidia-smi get the 'real' ID of GPUs ? I could use the UUID to get
