cloud.utilities.consolidate.consolidate(
    array_uri
    fragments
    *
    config=None
    max_fragment_size=MAX_FRAGMENT_SIZE_BYTES
)

Consolidate fragments

Parameters

Name	Type	Description	Default
array_uri	str	array URI	required
fragments	Sequence[tiledb.FragmentInfo]	list of fragments	required
config	Optional[Mapping[str, Any]]	config dictionary, defaults to None	None
max_fragment_size	int	max size of consolidated fragments, defaults to MAX_FRAGMENT_SIZE_BYTES	MAX_FRAGMENT_SIZE_BYTES

consolidate_and_vacuum

cloud.utilities.consolidate.consolidate_and_vacuum(
    array_uri
    *
    config=None
    vacuum_fragments=False
)

Consolidate and vacuum commits and fragment metadata, with an option to vacuum fragments as the first step.

Parameters

Name	Type	Description	Default
array_uri	str	array URI	required
config	Optional[Mapping[str, Any]]	config dictionary, defaults to None	None
vacuum_fragments	bool	vacuum fragments first, defaults to False	False

consolidate_fragments

cloud.utilities.consolidate.consolidate_fragments(
    array_uri
    *
    acn=None
    config=None
    group_by_first_dim=False
    graph=None
    dependencies=None
    consolidate_resources=None
    namespace=None
    max_fragment_size=MAX_FRAGMENT_SIZE_BYTES
)

Consolidate fragments in an array.

If group_by_first_dim is True, fragments with the same value for the first dimension will be consolidated together. Otherwise, all fragments will be consolidated together.

If graph is provided, the consolidation task nodes will be submitted to the graph. If dependencies is provided, the consolidation nodes will depend on the nodes in the list.

If graph is not provided, a new graph will be created and submitted to TileDB Cloud.

Parameters

Name	Type	Description	Default
array_uri	str	array URI	required
acn	Optional[str]	Access Credentials Name (ACN) registered in TileDB Cloud (ARN type), defaults to None	None
config	Optional[Mapping[str, Any]]	config dictionary, defaults to None	None
group_by_first_dim	bool	group fragment by first dimension, defaults to True	False
graph	Optional[dag.DAG]	graph to submit nodes to, defaults to None	None
dependencies	Optional[Sequence[dag.Node]]	list of nodes in the graph to depend on, defaults to None	None
consolidate_resources	Optional[Mapping[str, str]]	resources for the consolidate node, defaults to None	None
namespace	Optional[str]	TileDB Cloud namespace, defaults to the user’s default namespace	None
max_fragment_size	int	max size of consolidated fragments, defaults to MAX_FRAGMENT_SIZE_BYTES	MAX_FRAGMENT_SIZE_BYTES

group_fragments

cloud.utilities.consolidate.group_fragments(
    array_uri
    *
    config=None
    group_by_first_dim=True
)

Get a list of fragment info objects, optionally grouping fragments that have the same value for the first dimension.

Parameters

Name	Type	Description	Default
array_uri	str	array URI	required
config	Optional[Mapping[str, Any]]	config dictionary, defaults to None	None
group_by_first_dim	bool	group by first dimension, defaults to True	True

Returns

Name	Type	Description
	Sequence[Sequence[tiledb.FragmentInfo]]	list of lists of fragment info objects
