Trait for managing intermediate files to control memory usage for a particular index.

Required Methods

fn create<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, file_group: &'life1 str, file_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Writer, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Creates and opens a new intermediate file associated with a specific file_group for writing. The implementation should ensure that the file does not already exist.

• file_group: a unique identifier for the group of files
• file_id: a unique identifier for the new file

fn read_all<'life0, 'life1, 'async_trait>( &'life0 self, file_group: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<(String, Reader)>, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieves all intermediate files and their associated file identifiers for a specific file_group.

file_group is a unique identifier for the group of files.
