[mongodb-dev] How to reduce MongoDB size after remove data

[Aroxo Senraj]

1. First I have checked MongoDB Size 36GB
2. I have removed few tables data
3. Again I have checked MongoDB Size (36GB) not reduced. After I have
searched google and solution.

I have tried few below methods and take more time, slow my application
(hang)
Method 1: db.repairDatabase
Method 2:
db.getMongo().getDBNames().forEach(function(dbName) {
if ("local" != dbName && "admin" != dbName && "system" != dbName) {
var subject = db.getSiblingDB(dbName);
subject.getCollectionNames().forEach(function (collectionName) {
print('Compacting: ' +dbName + " - " + collectionName);
subject.runCommand({ compact: collectionName });
});
}
});

So, I need better solution. If any one know about this kindly let me know.

Hi Aroxo,

Questions related to the use of MongoDB (i.e. your question) are better
sent to mongodb-user group
<https://groups.google.com/forum/#!forum/mongodb-user>. This group
(mongodb-dev) is for discussion for/by/about developers/development/code of
MongoDB.

Please post a new discussion on mongodb-user group
<https://groups.google.com/forum/#!forum/mongodb-user> with the following
information:

- MongoDB server version
- Storage engine
- How did you check the "MongoDB size" ? i.e. filesystem commands or
mongo shell commands

Regards,
Wan.
