You have an AWS Lambda function developed with Serverless Framework, but you need to manage it with Terraform. Let's see how you can achieve this.
Recently, I have been looking for a way to implement thread synchronization in a Grails application which is hosted on several nodes on Rackspace. And while it's rather easy to synchronize threads within a single servlet container, it might be difficult to do it when the same data is simultaneously updated from separate server nodes. This post shows how this task can be solved with Hazelcast.
In my previous GORM related article, "Association Types in GORM", I have described how to create different types of relationships using Grails ORM. In this article, I would like to talk about several advanced GORM features that may help you in the development process, such as:
This post shows how to create Grails tag library for adding and removing identical HTML blocks, which can be used when you want to give user an option to dynamically add extra inputs for additional information. There are lots of simple JQuery and pure JavaScript solutions for this feature, but, in general, they are not flexible and clean enough for a Grails application. Pure tag library approach helps to avoid HTML and JS clutter in a GSP file and speeds up the development, since the only thing you need is to specify the tag with necessary parameters.
GORM (Grails Object Relational Mapping) is a plugin integrated with Grails and based on Java ORM - Hibernate. In this article, I'm going to describe how to make different kinds of associations in GORM.
The 'mysqldump' command is used to dump databases managed by MySQL. Let's consider three the most useful cases of MySQL database dumping.
If you have a project and want to checkout specific revision (commit), you can do it as described below.
Suppose you have a system with ElasticSearch server installed and need to upgrade it to a newer version. Below is a step-by-step guide explaining how you can do it, but note that it only works for ElasticSearch pre-1.x versions. It's also assumed that you have already stopped your ElasticSearch cluster before upgrading.
Assume you have a page with pagination that displays some objects table (selected from DB with GORM criteria) in your Grails application. If you want to know total number of possible results (as if there are no pagination parameters), you can do it in this way:
