2.0

Highlights

1. Support for TM1 v12

TM1py now works with TM1 v12.

with TM1Service(
        address="us-east-2.aws.planninganalytics.ibm.com",
        api_key="AB4VfG7T8wPM-912uFKeYG5PGh0XbS80MVBAt7SEG6xn",
        iam_url="https://iam.cloud.ibm.com/identity/token",
        tenant="YA9A2T8BS2ZU",
        database="Database") as tm1:
    print(tm1.server.get_product_Version())

by @rclapp in #1000

2. CRUD operations to manage servers on v12

with ManageService(domain=domain, root_client=root_client, root_secret=root_secret) as manager:
   manager.create_database(instance_name="instance name",
                          database_name="database_name",
                          product_version="12.0.0",
                          number_replicas=1,
                          cpu_requests="1000m",
                          cpu_limits="2000m",
                          memory_limits="2G",
                          memory_requests="1G",
                          storage_size="20Gi")

   manager.scale_database(instance_name="instance name", database_name="database name", replicas=2)

   manager.create_database_backup(instance_name="instance name", 
                                 database_name="database name", 
                                 backup_set_name="my backup")

3. Asynchronous execute_mdx functions

Speed up your MDX executions by assigning more than one worker-thread in TM1.

mdx = """
SELECT
{TM1SubsetAll([Big Dimension])} ON ROWS,
{TM1SubsetAll([Small Dimension])} ON COLUMNS
FROM [Big Cube]
"""

with TM1Service(**tm1params) as tm1:
    cells = tm1.cells.execute_mdx(
        mdx=mdx,
        # leverage 4 worker threads in TM1 for the extraction
        max_workers=4,
        # parallelization on rows axis
        async_axis=1)

by @vmitsenko in #935 and #1030

4. Hierarchy updates from data frames

Create and update TM1 hierarchies directly from pandas dataframes.

Stores	ElementType	Alias:a	City:s	Square Footage:n	level001	level000	level001_weight	level000_weight
S151	Numeric	Boardwalk Games	New York City	120	USA	World	1	1
S143	Numeric	Strategy Vault	Zurich	250	Switzerland	World	1	1
S811	Numeric	Cardboard Castle	Sydney	80	Sydney	World	1	1

columns = ["Stores", "ElementType", "Alias:a", "City:s", "Square Footage:n", "level001",
           "level000", "level001_weight", "level000_weight"]
data = [
    ['S151', "Numeric", "Boardwalk Games", "New York City", 120, "USA", "World", 1, 1],
    ['S143', 'Numeric', "Strategy Vault", "Zurich", 250, "Switzerland", "World", 1, 1],
    ['S811', 'Numeric', "Cardboard Castle", "Sydney", 80, "Sydney", "World", 1, 1],
]

with TM1Service(**tm1params) as tm1:
    tm1.hierarchies.update_or_create_hierarchy_from_dataframe(
        dimension_name="Stores",
        hierarchy_name="Stores",
        df=DataFrame(data=data, columns=columns)
    )
