Trove provides a RESTful API interface that is same regardless of the type of database. https://ronaldbradford.com/blog/mongodb-experience-server-logging-2010-06-11/ Fri, 11 Jun 2010 18:31:52 +0000 https://ronaldbradford.com/blog/mongodb-experience-server-logging-2010-06-11/ By default the mongod process sends all output to stdout. You can also specify the daemon to log to file which is necessary for any production implementation. For example: $ mongod --logpath=`pwd`/mongo. https://ronaldbradford.com/blog/mongodb-experience-keyvalue-store-2010-06-11/ Fri, 11 Jun 2010 17:14:37 +0000 https://ronaldbradford.com/blog/mongodb-experience-keyvalue-store-2010-06-11/ MongoDB is categorized as a schema-less, schema-free or a document orientated data store. Another category of NoSQL product is the key/value store. It had not dawned on me until a discussion with some of the 10gen employees that MongoDB is also a key/value store, this is just a subset of features. https://ronaldbradford.com/blog/mongodb-experience-stats-example-app-2010-06-10/ Thu, 10 Jun 2010 17:30:04 +0000 https://ronaldbradford.com/blog/mongodb-experience-stats-example-app-2010-06-10/ The best way to learn any new product is to a) read the manual, and b) start using the product. I created a simple sample application so I could understand the various functions including adding data, searching as well as management functions etc. https://ronaldbradford.com/blog/mongodb-experience-replication-101-2010-06-10/ Thu, 10 Jun 2010 15:06:50 +0000 https://ronaldbradford.com/blog/mongodb-experience-replication-101-2010-06-10/ After successfully installing and testing mongoDB it’s very easy to create a replication environment. $ mkdir -p data/{master,slave} $ mongod --dbpath=`pwd`/data/master --master --port 28011 > master.log 2>&1 & # Always check your log file $ cat master. https://ronaldbradford.com/blog/mongodb-experience-gotcha-with-collection-names-2010-06-09/ Wed, 09 Jun 2010 16:36:49 +0000 https://ronaldbradford.com/blog/mongodb-experience-gotcha-with-collection-names-2010-06-09/ In my earlier tests I bulk loaded data with the following command. mongoimport -d olympics -c olympic_event -type tsv --headerline -f name,id,sport,demonstration_competitions,olympic_games_contested,competitions,contested_as_demonstration_event --drop olympic_event.tsv connected to: 127.0.0.1 dropping: olympics.olympic_event imported 775 objects As you can see I imported 775 objects, however when I went to review them via the mongo interactive shell I found no data. https://ronaldbradford.com/blog/mongodb-experience-whats-running-in-the-db-2010-06-09/ Wed, 09 Jun 2010 16:07:24 +0000 https://ronaldbradford.com/blog/mongodb-experience-whats-running-in-the-db-2010-06-09/ You can very easily find out the running threads in the database (e.g. like a MySQL SHOW PROCESSLIST) with db.currentOp . > db.currentOp(); { "inprog" : [ ] } No much happening, however under some load you can see https://ronaldbradford.com/blog/mongodb-experience-bulk-loading-data-2010-06-09/ Wed, 09 Jun 2010 15:49:21 +0000 https://ronaldbradford.com/blog/mongodb-experience-bulk-loading-data-2010-06-09/ mongoDB has a mongoimport command. The docs only shows the usage but not any examples. here are my first examples. data1.csv 1 2 3 4 5 6 7 8 9 0 You need to specify your database (-d) and collection (-c) for importing. https://ronaldbradford.com/blog/mongodb-experience-online-resources-2010-06-09/ Wed, 09 Jun 2010 14:55:09 +0000 https://ronaldbradford.com/blog/mongodb-experience-online-resources-2010-06-09/ Following the initial Quickstart docs you will find a lot of online documentation. The following are good places to start. Tutorial The Interactive Shell Manual Admin Zone Starting and Stopping Monitoring and Diagnostics Backups There is also a Getting Started however I found this a duplication of the Quickstart. https://ronaldbradford.com/blog/mongodb-experience-getting-started-2010-06-09/ Wed, 09 Jun 2010 13:47:17 +0000 https://ronaldbradford.com/blog/mongodb-experience-getting-started-2010-06-09/ Getting started with MongoDB is relatively straight forward, following the instructions from the Quickstart guide has you operational in a few minutes. I like projects that provide a latest version link for software. https://ronaldbradford.com/blog/mongodb-experience-history-2010-06-09/ Wed, 09 Jun 2010 13:21:04 +0000 https://ronaldbradford.com/blog/mongodb-experience-history-2010-06-09/ My first exposure to MongoDB was in July 2008 when I was a panelist on “A Panel on Cloud Computing” at the Entrepreneurs Round Table in New York. The panel included a representative from 10gen the company behind the open source database product and at the time Mongo was described as a full stack solution with the database being only one future component.
