persistent-storage

问题 I was under the impression that both RDD execution and caching are lazy: Namely, if an RDD is cached, and only part of it was used, then the caching mechanism will only cache that part, and the other part will be computed on-demand. Unfortunately, the following experiment seems to indicate otherwise: val acc = new LongAccumulator() TestSC.register(acc) val rdd = TestSC.parallelize(1 to 100, 16).map { v => acc add 1 v } rdd.persist() val sliced = rdd .mapPartitions { itr => itr.slice(0, 2) }

问题 I am trying to setup couchbase operator 1.2 on my local system. i followed the following steps : Install the Couchbase Admission Controller. Deploy the Couchbase Autonomous Operator. Deploy the Couchbase Cluster. Access CouchBase from UI. But the problem with this is that as soon as the system or docker resets or the pod resets, the cluster's data is lost. So for the same I tried to do it by adding persistent volume with local storage class as mentioned in the docs but the result was still

问题 I am trying to create a Kubernetes pod with a single container which has two external volumes mounted on it. My .yml pod file is: apiVersion: v1 kind: Pod metadata: name: my-project labels: name: my-project spec: containers: - image: my-username/my-project name: my-project ports: - containerPort: 80 name: nginx-http - containerPort: 443 name: nginx-ssl-https imagePullPolicy: Always volumeMounts: - mountPath: /home/projects/my-project/media/upload name: pd-data - mountPath: /home/projects/my

问题 while trying to install openshift 3.11 ( okd ) , they ask to setup a persistent storage for each node because it's needed for the container deamon and for etcd/web console container for master nodes. You must configure storage for all master and node hosts because by default each system runs a container daemon. For containerized installations, you need storage on masters. Also, by default, the web console and etcd, which require storage, run in containers on masters. Containers run on nodes,

问题 This is the code I have used for cache persistance using 'apollo3-cache-persist', seems to have automatically purge the cached data after initial caching. Purging causes everything in the storage used for persistence to be cleared. Hence resulting in not persisting. import { persistCache, LocalStorageWrapper, LocalForageWrapper } from 'apollo3-cache-persist'; const httpLink = createHttpLink({ uri: 'http://localhost:4000/' }); const cache = new InMemoryCache(); persistCache({ cache, storage:

问题 I know that Heroku's dyno gets refreshed each time a deploy is made so is there anyway I can have my files persistent or there's no other way but use services like amazon S3? I use paperclip to handle file upload and most of the files will be in pdf. 回答1: It would be best to use S3 or another service. Ephemeral filesystem Each dyno gets its own ephemeral filesystem, with a fresh copy of the most recently deployed code. During the dyno’s lifetime its running processes can use the filesystem as
