in-memory

问题 I need to compile assembly in memory, that can compile another one. There is a form with one button. Here is a code of the form Imports System Imports System.Threading Imports System.CodeDom Imports System.CodeDom.Compiler Imports System.Collections Imports System.ComponentModel Imports System.Diagnostics Imports System.Drawing Imports System.IO Imports System.Windows.Forms Imports Microsoft.VisualBasic Public Class testtwo Shared str_tb As String Private Sub Button1_Click(ByVal sender As

问题 I need to do a lot of things with resources on the fly: parsing xsd/xml docs, building and compiling java classes, package them into jars ans wars, persist in DB, deploy them as OSGi, etc. Most of the libraries/API's, which I use, allow to perform all these intermediate tasks in memory, but there are some "special" libraries operating with java.io.File only. And there's nothing left for me but using real temporary files and directories which is not good in Java EE environment. I believe there

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . Are there any DBs for Java that can be run in an embedded mode with some tables being stored in-memory while loading others from disk? H2 and JavaDB seem to be the two leaders for Java DBs and I know they both have an in-memory mode, but do they make you load the whole DB into memory or can you decide on a table

问题 I am writing a unit test, and one of them is returning a zip file and I want to check the content of this zip file, grab some values from it, and pass the values to the next tests. I'm using Rack Test, so I know the content of my zip file is inside last_response.body . I have looked through the documentation of RubyZip but it seems that it's always expecting a file. Since I'm running a unit test, I prefer to have everything done in the memory as not to pollute any folder with test zip files,

问题 I have been researching this for the past couple days but cannot seem to find an example or documentation for anything that reads from an SFTP server and writes the contents to memory and not a file. It got me thinking if this is even possible. I was hoping to write the file downloaded from the SFTP stream to a byte array in memory and then work with that while the byte array was in memory. Is this possible? 回答1: The most common Java SFTP library, the JSch, allows this. Use one of its

问题 We need to implement a distributed priority queue within Hazelcast at the moment and the only documentation we can find on the matter is this: https://blog.hazelcast.com/priority-queueing-using-spi/, which is not a production ready implementation. It references MigrationAwareService and BackupAwareOperation interfaces and provides a basic example for how to implement them, but after inspecting Hazelcast's own QueueService it doesn't look like these examples will suffice. Is it better to use

问题 If a create a in-memory sqlite database using syntax below, then what is the size of maximum memory allocated to it? my $dbh = DBI->connect('dbi:SQLite:dbname=:memory:'); What will happen if size of in-memory database becomes greater than max available memory. Suppose I have 1 GB free and the database size become 1.1 GB, then will some data be written to disk or what? Is there a way to change the value of max-memory allocated to a in-memory sqlite database? 回答1: It will use virtual memory,

问题 I have a project which provides users with a list of current tasks that need to be completed. Any user can complete any task, and so to ensure that only one user is working on a task at a time I need to be able to 'lock' it. I'm using SignalR for this, so a user requests a lock on a task, and if they are successful (ie. if noone else has locked it) then they will be able to access the further information that they need. My problem is how to store the list of locked tasks. The original plan

问题 I have a Symfony2 application that loads users from in_memory user provider. The security.yml is the following: security: encoders: Symfony\Component\Security\Core\User\User: plaintext role_hierarchy: ROLE_ADMIN: ROLE_USER ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH] providers: in_memory: users: admin: { password: mypassword, roles: [ 'ROLE_ADMIN' ] } firewalls: dev: pattern: ^/(_(profiler|wdt)|css|images|js)/ security: false login: pattern: ^/demo/secured/login$ security

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Is there a database which will satisfy all (or at least most) of this requirements? Graph oriented - optimized for storing graphs and traversal(e.g HyperGraphDB, Neo4j) Running in memory, but having a persisted storage (e.g. Redis) Distributed (e.g. membase) Had .NET adapter (TCP/IP, not HTTP REST) Or am I
