 # couchbase-java-importer
-This is a pluggable importer for Couchbase
+
+This is a pluggable importer for Couchbase. So far it supports importing documents from a CSV file, a MongoDB or CouchDB instance.
+
+## How to Build
+
+```
+$ ./gradlew build
+```
+
+## How to Use
+
+```
+$ cd build/distributions/
+$ unzip couchbase-java-importer.zip
+```
+
+At this step you need to choose what kind of import you want to do. Configuration samples are available at the root of the repository. Let's pretend you want to import a MongoDB collection called `restaurants` from the database `test` and add a field called `couchbaseType` with the value `restaurant` for every imported documents. Let's also pretend you have a local MongoDB and local Couchbase instance. For that you would need the following configuration
+
+```
+# Hostnames, comma separated list of Couchbase node IP or hostname
+hostnames: localhost,127.0.0.1
+# Buket name
+bucket: default
+# Bucket password
+password:
+# Log to write succesfully imported keys
+successLogFilename: succes.out
+# Log to write unsuccesfully imported keys
+errorLogFilename: error.out
+# Default RequestCancelledException delay in milliseconds and maximum number of retries
+requestCancelledExceptionDelay: 31000
+requestCancelledExceptionRetries: 100
+# Default TemporaryFailureException delay in milliseconds and maximum number of retries
+temporaryFailureExceptionDelay: 100
+temporaryFailureExceptionRetries: 100
+# Default upsert timeout in milliseconds
+importTimeout: 500
+# Choose between CSV, COUCHDB, MONGODB
+choosenImporter: MONGODB
+mongodb:
+  # Give a valid connection string to connect to a MongoDB instance
+  connectionString: "mongodb://127.0.0.1:27017/"
+  # Name of the MondoDB database to connect to
+  dbName: "test"
+  # Name of the collection to import
+  collectionName: "restaurants"
+  # Couchbase does not have collection, we usually use a type field. As there could already be a type field in Mongo, you can specify another fieldName to be used as type
+  typeField: "type"
+  # type of the documents that will be imported
+  type: "restaurant"
+```
+
+This is the content of the MongoDB sample configuration. To run the import copy the configuration file and run the importer:
+
+```
+$ cp ../../../application-mongodb.yml.sample application.yml 
+$ ./bin/couchbase-java-importer
+```
+
+Once the import as ran you should have one file called `success.out` that contains the id of every document imported. If something went wrong you should also have a file called `error.out`.
+
+Every configuration samples contains comments that should help you understand the various import options.
