Pada 15 September 2026, semua lingkungan Cloud Composer 1 dan Cloud Composer 2 versi 2.0.x akan mencapai akhir masa pakainya yang direncanakan, dan Anda tidak akan dapat menggunakannya. Sebaiknya rencanakan migrasi ke Cloud Composer 3.
Ikuti petunjuk di halaman ini untuk mengaktifkan atau menonaktifkan serialisasi DAG.
Di lingkungan Cloud Composer, penjadwal Airflow dan
server web Airflow terus memproses DAG. Anda dapat meningkatkan
keandalan dan performa server web Airflow dengan mengaktifkan
serialisasi DAG.
Mengaktifkan serialisasi DAG akan memaksa penjadwal untuk memproses file DAG
sebelum dikirim ke server web. Server web tidak memproses DAG.
Sebagai gantinya, ia membaca DAG yang diserialisasi dari database Airflow. Dengan serialisasi DAG dengan cara ini, penggunaan CPU dan memori server web akan berkurang, terutama saat memproses DAG dalam jumlah besar.
Sebelum memulai
Serialisasi DAG memengaruhi fitur Cloud Composer berikut:
Serialisasi DAG tidak dapat diaktifkan secara bersamaan dengan
pemuatan DAG asinkron.
Mengaktifkan serialisasi DAG akan menonaktifkan semua plugin server web Airflow untuk
Cloud Composer. Hal ini tidak memengaruhi plugin penjadwal atau pekerja,
termasuk operator Airflow, sensor, dan sebagainya.
Mengaktifkan serialisasi DAG
Anda dapat mengaktifkan serialisasi DAG untuk lingkungan yang ada atau saat membuat
lingkungan baru.
Untuk mengaktifkan serialisasi DAG,
ganti opsi konfigurasi Airflow berikut:
Bagian
Kunci
Nilai
core
store_serialized_dags
True
core
store_dag_code
True
core
min_serialized_dag_update_interval
30
scheduler
dag_dir_list_interval
30
Opsi konfigurasi Airflow min_serialized_dag_update_interval
mengontrol seberapa sering DAG serial
diperbarui dalam database.
Opsi dag_dir_list_interval
mengontrol seberapa sering DAG yang dihapus dihapus dari database
Airflow. Frekuensi update yang tinggi dapat berdampak negatif pada performa. Sebaiknya
tetapkan min_serialized_dag_update_interval dan
dag_dir_list_interval ke 30 detik.
Menonaktifkan serialisasi DAG
Anda dapat mengaktifkan serialisasi DAG untuk lingkungan yang ada atau saat membuat
lingkungan baru.
Untuk menonaktifkan serialisasi DAG, ganti opsi konfigurasi

You can improve\nthe reliability and performance of the Airflow web server by enabling\n[DAG serialization](https://airflow.apache.org/docs/apache-airflow/stable/dag-serialization.html).\n\nEnabling DAG serialization forces the scheduler to process DAG files\nbefore they are sent to the web server. The web server does not process DAGs.\nInstead, it reads the serialized DAGs from the Airflow database. Serializing\nDAGs in this way reduces the CPU and memory usage of the web server,\nespecially when processing a large number of DAGs.\n\nBefore you begin\n----------------\n\n| **Note:** Starting from Cloud Composer version **1.15.0** , DAG serialization is enabled by default. You can enable and disable DAG serialization in new and existing environments by [overriding Airflow configuration options](/composer/docs/composer-2/override-airflow-configurations), as described in the following sections.\n\nDAG serialization affects the following Cloud Composer features:\n\n- DAG serialization cannot be enabled at the same time as [asynchronous DAG loading](/composer/docs/composer-2/access-airflow-web-interface#asynchronous-load).\n- Enabling DAG serialization disables all Airflow web server plugins for Cloud Composer. This does not impact scheduler or worker plugins, including Airflow operators, sensors, and so on.\n\nEnabling DAG serialization\n--------------------------\n\nYou can enable DAG serialization for an existing environment or when creating a\nnew environment.\n| **Note:** Do not apply these settings to environments running Airflow 2.x. The DAG serialization and storing DAG code in Airflow Metadata Database is by default turned on in Airflow 2.x and you cannot switch it on or off.\n\nTo enable DAG serialization,\n[override](/composer/docs/composer-2/override-airflow-configurations) the following Airflow configuration options:\n\nThe [`min_serialized_dag_update_interval`](https://airflow.apache.org/docs/stable/configurations-ref.html#min-serialized-dag-update-interval)\nAirflow configuration option controls how frequently serialized DAGs\nare updated in the database.\nThe [`dag_dir_list_interval`](https://airflow.apache.org/docs/stable/configurations-ref.html#dag-dir-list-interval)\noption controls how frequently removed DAGs are deleted from the Airflow\ndatabase. A high update frequency can negatively impact performance. We\nrecommend setting `min_serialized_dag_update_interval` and\n`dag_dir_list_interval` to 30 seconds.\n\nDisabling DAG serialization\n---------------------------\n\nYou can enable DAG serialization for an existing environment or when creating\na new environment.\n\nTo disable DAG serialization, [override](/composer/docs/composer-2/override-airflow-configurations) the following Airflow\nconfiguration options:"]]
