+# Parquet Sink/Output Codec
+
+This is an implementation of Parquet Sink Codec that parses the Dataprepper Events into Parquet Records and writes them into the underlying OutputStream.
+
+## Usages
+
+Parquet Output Codec can be configured with sink plugins (e.g. S3 Sink) in the Pipeline file.
+
+## Configuration Options

+
+## AWS Configuration
+
+### Codec Configuration:
+
+1) `schema`: A json string that user can provide in the yaml file itself. The codec parses schema object from this schema string. 
+2) `schema_file_location`: Path to the schema json file through which the user can provide schema.
+3) `exclude_keys`: Those keys of the events that the user wants to exclude while converting them to avro records.
+4) `schema_registry_url`: Another way of providing the schema through schema registry.
+5) `region`: AWS Region of the S3 bucket which the user wants to use as buffer for records parsed by Parquet Output Codec.
+6) `bucket`: Name of the S3 bucket which the user wants to use as buffer for records parsed by Parquet Output Codec.
+7) `path_prefix`: Path to the folder within the S3 bucket where the user wants the intermittent files to be made.
+8) `schema_bucket`: Name of the S3 bucket in which `schema.json` file is kept.
+9) `file_key`: File key of `schema.json` file kept in S3 bucket.
+10) `schema_region`: AWS Region of the S3 bucket in which `schema.json` file is kept.
+
+### Note:
+
+1) User can provide only one schema at a time i.e. through either of the ways provided in codec config.
+2) If the user wants the tags to be a part of the resultant Avro Data and has given `tagsTargetKey` in the config file, the user also has to modify the schema to accommodate the tags. Another field has to be provided in the `schema.json` file:
+
+    `{
+   "name": "yourTagsTargetKey",
+   "type": { "type": "array",
+   "items": "string"
+   }`
+
+3) The user must provide valid `region`, `bucket` and `path_prefix` for the codec to work. 
+4) If the user wants to input schema through a `schema.json` file kept in S3, the user must provide corresponding credentials i.e. region, bucket name and file key of the same.
