+# Native MongoDB client dependencies
+
+This module prepares the Java dependencies for the native MongoDB connector. It
+bundles the official synchronous driver, its core, BSON, and BSON record codec
+at one version, using a module-local BOM so other connector plugins keep their
+own dependencies. The archive also carries the Snappy and Zstandard Java providers
+so FE metadata reads accept the same compression URI options as the native BE.
+The FE host supplies logging APIs and bindings.
+
+The dependency-only archive does not register a `ConnectorProvider` and cannot
+create a MongoDB catalog. The FE build stages it as
+`plugins/connector/mongodb.zip`, without unpacking it into an auto-loaded plugin
+directory. A later connector implementation will add the provider and enable the
+normal plugin deployment path.
+
+The BE uses the MongoDB C Driver (`libmongoc` and `libbson`) built together by:
+
+```sh
+bash thirdparty/build-thirdparty.sh mongo_c_driver
+```
+
+The native build produces PIC static archives with OpenSSL, Cyrus SASL, SRV DNS,
+Snappy, zstd and zlib support. It reuses Doris-managed dependencies and the driver's
+bundled utf8proc for SCRAM-SHA-256. It does not require the C++ driver, a BE JVM,
+Reactive Streams, or client-side encryption libraries. The reader and BSON
+`DataTypeSerDe` implementation are separate changes. The BE CMake targets `bson2`
+and `mongoc2` expose the static headers, definitions and dependency closure; they
+are not added to the common BE link set until a reader consumes them.
