pydantic model VectorData#

Bases: Data

An n-dimensional dataset representing a column of a DynamicTable. If used without an accompanying VectorIndex, first dimension is along the rows of the DynamicTable and each step along the first dimension is a cell of the larger table. VectorData can also be used to represent a ragged array if paired with a VectorIndex. This allows for storing arrays of varying length in a single cell of the DynamicTable by indexing into this VectorData. The first vector is at VectorData[0:VectorIndex(0)+1]. The second vector is at VectorData[VectorIndex(0)+1:VectorIndex(1)+1], and so on.

pydantic model DynamicTableRegion#

Bases: VectorData

DynamicTableRegion provides a link from one table to an index or region of another. The table attribute is a link to another DynamicTable, indicating which table is referenced, and the data is int(s) indicating the row(s) (0-indexed) of the target array. DynamicTableRegion`s can be used to associate rows with repeated meta-data without data duplication. They can also be used to create hierarchical relationships between multiple `DynamicTable`s. `DynamicTableRegion objects may be paired with a VectorIndex object to create ragged references, so a single cell of a DynamicTable can reference many rows of another DynamicTable.

pydantic model DynamicTable#

Bases: Container

A group containing multiple datasets that are aligned on the first dimension (Currently, this requirement if left up to APIs to check and enforce). Apart from a column that contains unique identifiers for each row there are no other required datasets. Users are free to add any number of VectorData objects here. Table functionality is already supported through compound types, which is analogous to storing an array-of-structs. DynamicTable can be thought of as a struct-of-arrays. This provides an alternative structure to choose from when optimizing storage for anticipated access patterns. Additionally, this type provides a way of creating a table without having to define a compound type up front. Although this convenience may be attractive, users should think carefully about how data will be accessed. DynamicTable is more appropriate for column-centric access, whereas a dataset with a compound type would be more appropriate for row-centric access. Finally, data size should also be taken into account. For small tables, performance loss may be an acceptable trade-off for the flexibility of a DynamicTable. For example, DynamicTable was originally developed for storing trial data and spike unit metadata. Both of these use cases are expected to produce relatively small tables, so the spatial locality of multiple datasets present in a DynamicTable is not expected to have a significant performance impact. Additionally, requirements of trial and unit metadata tables are sufficiently diverse that performance implications can be overlooked in favor of usability.
