) -> PyResult<()>
pub fn consolidate_catalog_by_period( &mut self, period_nanos: Option<u64>, start: Option<u64>, end: Option<u64>, ensure_contiguous_files: Option<bool>, ) -> PyResult<()>
Consolidate all data files in the catalog by splitting them into fixed time periods.
This method identifies all leaf directories in the catalog that contain parquet files
and consolidates them by period. A leaf directory is one that contains files but no subdirectories.
This is a convenience method that effectively calls consolidate_data_by_period
for all data types
and instrument IDs in the catalog.
§Parameters
period_nanos
: Optional period duration for consolidation in nanoseconds. Default is 1 day (86400000000000). Examples: 3600000000000 (1 hour), 604800000000000 (7 days), 1800000000000 (30 minutes)start
: Optional start timestamp for the consolidation range (nanoseconds since Unix epoch)end

Sourcepub fn consolidate_data_by_period(

Consolidate data files by splitting them into fixed time periods.
This method queries data by period and writes consolidated files immediately, using efficient period-based consolidation logic. When start/end boundaries intersect existing files, the function automatically splits those files to preserve all data.
§Parameters
type_name
: The data type directory name (e.g., “quotes”, “trades”, “bars”)identifier
: Optional instrument ID to consolidate. If None, consolidates all instrumentsperiod_nanos
: Optional period duration for consolidation in nanoseconds. Default is 1 day (86400000000000). Examples: 3600000000000 (1 hour), 604800000000000 (7 days), 1800000000000 (30 minutes)start
: Optional start timestamp for consolidation range (nanoseconds since Unix epoch)end

Sourcepub fn delete_catalog_range(
&mut self,
start: Option<u64>,
end: Option<u64>,
) -> PyResult<()>
pub fn delete_catalog_range( &mut self, start: Option<u64>, end: Option<u64>, ) -> PyResult<()>
Delete data within a specified time range across the entire catalog.
This method identifies all leaf directories in the catalog that contain parquet files
and deletes data within the specified time range from each directory. A leaf directory
is one that contains files but no subdirectories. This is a convenience method that
effectively calls delete_data_range
for all data types and instrument IDs in the catalog.
§Parameters
start
: Optional start timestamp for the deletion range (nanoseconds since Unix epoch)end
: Optional end timestamp for the deletion range (nanoseconds since Unix epoch)
§Notes
- This operation permanently removes data and cannot be undone
- The deletion process handles file intersections intelligently by splitting files when they partially overlap with the deletion range
- Files completely within the deletion range are removed entirely
- Files partially overlapping the deletion range are split to preserve data outside the range
- This method is useful for bulk data cleanup operations across the entire catalog
- Empty directories are not automatically removed after deletion
Sourcepub fn delete_data_range(
&mut self,
type_name: &str,
instrument_id: Option<String>,
start: Option<u64>,
end: Option<u64>,
) -> PyResult<()>
pub fn delete_data_range( &mut self, type_name: &str, instrument_id: Option<String>, start: Option<u64>, end: Option<u64>, ) -> PyResult<()>
Delete data within a specified time range for a specific data type and instrument.
This method identifies all parquet files that intersect with the specified time range and handles them appropriately:
- Files completely within the range are deleted
- Files partially overlapping the range are split to preserve data outside the range
- The original intersecting files are removed after processing
§Parameters
type_name
: The data type directory name (e.g., “quotes”, “trades”, “bars”)instrument_id
: Optional instrument ID to delete data for. If None, deletes data across all instrumentsstart
: Optional start timestamp for the deletion range (nanoseconds since Unix epoch)end
: Optional end timestamp for the deletion range (nanoseconds since Unix epoch)
§Notes
- This operation permanently removes data and cannot be undone
- Files that partially overlap the deletion range are split to preserve data outside the range
- The method ensures data integrity by using atomic operations where possible
- Empty directories are not automatically removed after deletion
