A materialized view is a type of table that is automatically built from a Synapse
SQL query. Its content is read only and based off the defining_sql
attribute.
The SQL of the materialized view may contain JOIN clauses on multiple tables.
A MaterializedView
object represents this concept in Synapse:
https://rest-docs.synapse.org/rest/org/sagebionetworks/repo/model/table/MaterializedView.html
ATTRIBUTE | DESCRIPTION |
---|---|
id |
The unique immutable ID for this entity. Once issued, this ID is guaranteed to never change or be re-issued. |
name |
The name of this entity. Must be 256 characters or less. Names may only contain: letters, numbers, spaces, underscores, hyphens, periods, plus signs, apostrophes, and parentheses. |
description |
The description of this entity. Must be 1000 characters or less. |
etag |
Synapse employs an Optimistic Concurrency Control (OCC) scheme to handle concurrent updates. Since the E-Tag changes every time an entity is updated it is used to detect when a client's current representation of an entity is out-of-date. |
created_on |
The date this entity was created. |
modified_on |
The date this entity was last modified. In YYYY-MM-DD-Thh:mm:ss.sssZ format. |
created_by |
The ID of the user that created this entity. |
modified_by |
The ID of the user that last modified this entity. |
parent_id |
The ID of the Entity that is the parent of this entity. |
version_number |
The version number issued to this version on the object. |
version_label |
The version label for this entity. |
version_comment |
The version comment for this entity. |
is_latest_version |
If this is the latest version of the object. |
columns |
(Read Only) The columns of a materialized view are dynamic based on the select statement of the definingSQL. This list of columnIds is for read-only purposes.
TYPE:
|
is_search_enabled |
When creating or updating a table or view specifies if full text search should be enabled. |
defining_sql |
The synapse SQL statement that defines the data in the materialized view. |
annotations |
Additional metadata associated with the entityview. The key is
the name of your desired annotations. The value is an object containing a
list of values (use empty list to represent no values for key) and the
value type associated with all values in the list. To remove all
annotations set this to an empty dict
TYPE:
|
activity |
The Activity model represents the main record of Provenance in Synapse. |

query_part_mask
staticmethod
¶
query_part_mask(query: str, part_mask: int, *, synapse_client: Optional[Synapse] = None, **kwargs) -> QueryResultOutput
Query for data on a table stored in Synapse. This is a more advanced use case
of the query
function that allows you to determine what addiitional metadata
about the table or query should also be returned. If you do not need this
additional information then you are better off using the query
function.
The query for this method uses this Rest API: https://rest-docs.synapse.org/rest/POST/entity/id/table/query/async/start.html
PARAMETER | DESCRIPTION |
---|---|
query
|
The query to run. The query must be valid syntax that Synapse can understand. See this document that describes the expected syntax of the query: https://rest-docs.synapse.org/rest/org/sagebionetworks/repo/web/controller/TableExamples.html
TYPE:
|
part_mask
|
The bitwise OR of the part mask values you want to return in the results. The following list of part masks are implemented to be returned in the results: - Query Results (queryResults) = 0x1 - Query Count (queryCount) = 0x2 - The sum of the file sizes (sumFileSizesBytes) = 0x40 - The last updated on date of the table (lastUpdatedOn) = 0x80

Querying for data with a part mask
This example shows how to use the bitwise OR
of Python to combine the
part mask values and then use that to query for data in a table and print
out the results.
In this case we are getting the results of the query, the count of rows, and the last updated on date of the table.
from synapseclient import Synapse
from synapseclient.models import query_part_mask
syn = Synapse()
syn.login()
QUERY_RESULTS = 0x1
QUERY_COUNT = 0x2
LAST_UPDATED_ON = 0x80
# Combine the part mask values using bitwise OR
part_mask = QUERY_RESULTS | QUERY_COUNT | LAST_UPDATED_ON
result = query_part_mask(query="SELECT * FROM syn1234", part_mask=part_mask)
print(result)

get_acl
¶
get_acl(principal_id: int = None, check_benefactor: bool = True, *, synapse_client: Optional[Synapse] = None) -> List[str]
Get the ACL that a user or group has on an Entity.
Note: If the entity does not have local sharing settings, or ACL set directly on it, this will look up the ACL on the benefactor of the entity. The benefactor is the entity that the current entity inherits its permissions from. The benefactor is usually the parent entity, but it can be any ancestor in the hierarchy. For example, a newly created Project will be its own benefactor, while a new FileEntity's benefactor will start off as its containing Project or Folder. If the entity already has local sharing settings, the benefactor would be itself.
PARAMETER | DESCRIPTION |
---|---|
principal_id
|
Identifier of a user or group (defaults to PUBLIC users)
TYPE:
|
check_benefactor
|
If True (default), check the benefactor for the entity to get the ACL. If False, only check the entity itself. This is useful for checking the ACL of an entity that has local sharing settings, but you want to check the ACL of the entity itself and not the benefactor it may inherit from.

Sets permission that a user or group has on an Entity. An Entity may have its own ACL or inherit its ACL from a benefactor.
PARAMETER | DESCRIPTION |
---|---|
principal_id
|
Identifier of a user or group.
TYPE:
|

modify_benefactor
|
Set as True when modifying a benefactor's ACL. The term 'benefactor' is used to indicate which Entity an Entity inherits its ACL from. For example, a newly created Project will be its own benefactor, while a new FileEntity's benefactor will start off as its containing Project. If the entity already has local sharing settings the benefactor would be itself. It may also be the immediate parent, somewhere in the parent tree, or the project itself.

delete_permissions
¶

Delete the entire Access Control List (ACL) for a given Entity. This is not scoped to a specific user or group, but rather removes all permissions associated with the Entity. After this operation, the Entity will inherit permissions from its benefactor, which is typically its parent entity or the Project it belongs to.
In order to remove permissions for a specific user or group, you
should use the set_permissions
method with the access_type
set to
an empty list.
By default, Entities such as FileEntity and Folder inherit their permission from their containing Project. For such Entities the Project is the Entity's 'benefactor'. This permission inheritance can be overridden by creating an ACL for the Entity. When this occurs the Entity becomes its own benefactor and all permission are determined by its own ACL.
If the ACL of an Entity is deleted, then its benefactor will automatically be set to its parent's benefactor.
Special notice for Projects: The ACL for a Project cannot be deleted, you must individually update or revoke the permissions for each user or group.
PARAMETER | DESCRIPTION |

If True, log the changes that would be made instead of actually performing the deletions. When enabled, all ACL deletion operations are simulated and logged at info level. Defaults to False.
TYPE:
|
show_acl_details
|
When dry_run=True, controls whether current ACL details are displayed for entities that will have their permissions changed. If True (default), shows detailed ACL information. If False, hides ACL details for cleaner output. Has no effect when dry_run=False.
TYPE:
|
show_files_in_containers
|
When dry_run=True, controls whether files within containers are displayed in the preview. If True (default), shows all files. If False, hides files when their only change is benefactor inheritance (but still shows files with local ACLs being deleted). Has no effect when dry_run=False.

List the Access Control Lists (ACLs) for this entity and optionally its children.
This function returns the local sharing settings for the entity and optionally its children. It provides a mapping of all ACLs for the given container/entity.
Important Note: This function returns the LOCAL sharing settings only, not the effective permissions that each Synapse User ID/Team has on the entities. More permissive permissions could be granted via a Team that the user has access to that has permissions on the entity, or through inheritance from parent entities.
