+# MongoDB input plugin for Embulk
+
+MongoDB input plugin for Embulk loads records from MongoDB.
+
+**CAUTION:** this plugin does not support array and object fields, 
+because embulk does not supported these types yet.
+But these types will be supported, so when it supported I add support these types.
+For more detail see following issues.
+
+- https://github.com/embulk/embulk/issues/120
+- https://github.com/embulk/embulk/issues/121
+
+## Overview
+
+* **Plugin type**: input
+* **Resume supported**: no
+* **Cleanup supported**: no
+* **Guess supported**: no
+
+## Configuration
+
+- **uri**: [MongoDB connection string URI](http://docs.mongodb.org/manual/reference/connection-string/) (e.g. 'mongodb://localhost:27017/mydb') (string, required)
+- **collection**: source collection name (string, required)
+- **fields**: hash records that has the following two fields (array, required)
+  - name: Name of the column
+  - type: Column types as follows
+    - boolean
+    - long
+    - double
+    - string
+    - timestamp
+- **query**: provides a JSON document as a query that optionally limits the documents returned (string, optional)
+- **sort**: specifies an ordering for exported results (string, optional)
+
+## Example
+
+### Export all objects
+
+```yaml
+in:
+  type: mongodb
+  uri: mongodb://myuser@mypassword:localhost:27017/my_database
+  collection: "my_collection"
+  fields:
+    - { name: id, type: string }
+    - { name: field1, type: long }
+    - { name: field2, type: timestamp }
+```
+
+### Filter object by query and sort
+
+
+```yaml
+in:
+  type: mongodb
+  uri: mongodb://myuser@mypassword:localhost:27017/my_database
+  collection: "my_collection"
+  fields:
+    - { name: id, type: string }
+    - { name: field1, type: long }
+    - { name: field2, type: timestamp }
+  query: '{ field1: { $gte: 3 } }'
+  sort: '{ field1: 1 }'
+```
+
+## Build
+
+```
+$ ./gradlew gem
+```
