pub async fn alter_table_columns( &self, table_name: String, column_alterations: Vec<HashMap<String, String>>, ) -> Result<AlterTableColumnsResponse, KineticaError>
Modify various properties of multiple columns in a table (multiple alter/table requests for columns)
Apply various modifications to columns in a table, view. The available modifications include the following:
Create or delete an index on a particular column. This can speed up certain operations when using expressions containing equality or relational operators on indexed columns. This only applies to tables.
Manage a table’s columns–a column can be added, removed, or have its type and properties modified, including whether it is dictionary encoded or not.
table_name- Table on which the operation will be performed. Must be an existing table or view, in [schema_name.]table_name format, using standard name resolution rules.column_alterations- List of alter table add/delete/change column requests - all for the same table. Each request is a map that includes ‘column_name’, ‘action’ and the options specific for the action. Note that the same options as in alter table requests but in the same map as the column name and the action. For example: [‘column_name’:‘col_1’,‘action’:‘change_column’,‘rename_column’:‘col_2’,‘column_name’:‘col_1’,‘action’:‘add_column’, ‘type’:‘int’,‘default_value’:‘1’].

pub async fn alter_table_columns_raw( &self, request: &AlterTableColumnsRequest, ) -> Result<AlterTableColumnsResponse, KineticaError>
Sends a pre-built AlterTableColumnsRequest to the /alter/table/columns endpoint.
pub async fn alter_table_columns_from_url( &self, url: &str, request: &AlterTableColumnsRequest, ) -> Result<AlterTableColumnsResponse, KineticaError>
Sends a pre-built AlterTableColumnsRequest to a specific worker URL, bypassing HA head-node selection. Used for multi-head access.
