The `attribute` action manages extended attributes for in-memory tables in CAS. Extended attributes are user-defined metadata, stored as key-value pairs, that can be associated with a table or specific columns within a table. This action allows for adding, updating, dropping, and exporting these attributes, providing a flexible way to enrich data with additional context or information without altering the data itself.
The alterTable action allows for modifying the metadata and properties of an in-memory CAS table. This includes renaming the table, changing its label, modifying column properties such as names, labels, and formats, as well as dropping columns or reordering them. It is a versatile tool for managing table structures directly on the CAS server without needing to recreate tables.
Ajoute les lignes d'une table source à la fin d'une table cible en mémoire. Cette action est particulièrement utile pour consolider des données provenant de différentes sources ou pour agréger des lots de données dans une table principale sans avoir à recréer entièrement la table.
