I’m using the GridDB Python client to insert data into a container, but after inserting the data, I can’t seem to retrieve it. The code executes without any errors, but when I query the container, the inserted data is missing.

import griddb_python as griddb

factory = griddb.StoreFactory.get_instance()

try:
    # Connect to the GridDB store
    store = factory.get_store(
        notification_member="123.0.0.1",
        notification_port=31999,
        cluster_name="myCluster",
        username="admin",
        password="admin"
    )

    # Retrieve or create the container
    container = store.get_container("personContainer")
    if container is None:
        container_info = griddb.ContainerInfo(
            "personContainer",
            [
                griddb.ColumnInfo("id", griddb.GS_TYPE_INTEGER),
                griddb.ColumnInfo("name", griddb.GS_TYPE_STRING),
                griddb.ColumnInfo("age", griddb.GS_TYPE_INTEGER)
            ],
            griddb.CONTAINER_COLLECTION, True
        )
        container = store.put_container(container_info)

    # Insert data
    row = [1, "John Doe", 30]
    container.put(row)

except griddb.GSException as e:
    for i in range(e.get_error_stack_size()):
        print(f"[{i}] Error code: {e.get_error_code(i)}")
        print(f"Error message: {e.get_message(i)}")

The code runs without any errors, but when I query the container, I cannot find the inserted data. It seems that the data is not being persisted in the container after the put() operation.

What I’ve tried:

• Double-checked the GridDB server and confirmed it’s running.
• Verified that the container schema is correct and that the container exists.
• Looked through the documentation for common issues with put().

Why is the data not being persisted in GridDB after the insert operation, and how can I make sure that the inserted data is saved properly?
