 Consult the merge function documentation to understand exactly how specific fields are merged to avoid information loss. Please note that when merging data packages x and y, the [`project$samplingDesign`](/metadata/#project.samplingDesign) field in the resulting package will be set to the value of `project$samplingDesign` from data package x. Therefore, we recommend merging data packages only for projects that use the same sampling design.

+## Do I need to use CSV files?
+
+No. Some studies have media and observations tables with over a million records, which may be hard to produce or consume as CSV files. Here are two approaches for formatting large files:
+
+### gzipped CSV files
+
+By compressing a CSV file, you can often reduce its size by a factor. We recommend gzip over zip, as it allows direct file reading. Compressed CSV files are supported in all versions of Camtrap DP, by [frictionless-py][frictionless-py] and the [camtrapdp][camtrapdp] R package.
+
+1. Compress the file:
+
+    ```
+    gzip media.csv
+    ```
+
+2. Refer to the compressed CSV file in the `datapackage.json` as follows:
+
+    ```json
+    {
+      "name": "media",
+      "path": "media.csv.gz",
+      "profile": "tabular-data-resource",
+      "format": "csv",
+      "mediatype": "text/csv",
+      "encoding": "UTF-8",
+      "schema": "https://raw.githubusercontent.com/tdwg/camtrap-dp/1.0.2/media-table-schema.json"
+    }
+    ```
+
+### Apache parquet
+
+[Apache Parquet](https://parquet.apache.org/) is an open source data file format, designed for efficient data storage and retrieval. Parquet files are supported in Camtrap DP 1.0.2, by the [frictionless-py][frictionless-py] after installing an [extension](https://framework.frictionlessdata.io/docs/formats/parquet.html), but **not by the [camtrapdp][camtrapdp] R package** (as it is not yet supported by [its dependency](https://github.com/frictionlessdata/frictionless-r/issues/117)).
+
+1. Create the parquet file (e.g. with the arrow R package).
+
+2. Refer to the parquet file in the `datapackage.json` as follows:
+
+    ```json
+    {
+      "name": "media",
+      "path": "media.parquet",
+      "profile": "tabular-data-resource",
+      "format": "parquet",
+      "mediatype": "application/vnd.apache.parquet",
+      "encoding": "UTF-8",
+      "schema": "https://raw.githubusercontent.com/tdwg/camtrap-dp/1.0.2/media-table-schema.json"
+    }
