# batch
# `pdsx._internal.batch`
batch operations for concurrent CRUD operations.
## Functions
### `batch_delete`
```python theme={null}
batch_delete(client: AsyncClient, uris: list[str]) -> BatchResult
```
delete multiple records concurrently.
**Args:**
* `client`: authenticated atproto client
* `uris`: list of record URIs to delete
* `concurrency`: maximum concurrent operations (default: 10)
* `fail_fast`: stop on first error (default: False)
* `show_progress`: show progress bar (default: True)
**Returns:**
* batch result with successful and failed operations
### `batch_create`
```python theme={null}
batch_create(client: AsyncClient, collection: str, records: list[dict[str, RecordValue]]) -> BatchResult
```
create multiple records concurrently.
**Args:**
* `client`: authenticated atproto client
* `collection`: collection name
* `records`: list of record data dictionaries
* `rkeys`: optional list of rkeys (one per record, None for auto-generated)
* `concurrency`: maximum concurrent operations (default: 10)
* `fail_fast`: stop on first error (default: False)
* `show_progress`: show progress bar (default: True)
**Returns:**
* batch result with successful URIs and failed operations
### `batch_update`
```python theme={null}
batch_update(client: AsyncClient, updates: list[tuple[str, dict[str, RecordValue]]]) -> BatchResult
```
update multiple records concurrently.
**Args:**
* `client`: authenticated atproto client
* `updates`: list of (uri, updates\_dict) tuples
* `concurrency`: maximum concurrent operations (default: 10)
* `fail_fast`: stop on first error (default: False)
* `show_progress`: show progress bar (default: True)
**Returns:**
* batch result with successful URIs and failed operations
### `read_uris_from_stdin`
```python theme={null}
read_uris_from_stdin() -> list[str]
```
read URIs from stdin, one per line.
**Returns:**
* list of URIs read from stdin
### `read_records_from_stdin`
```python theme={null}
read_records_from_stdin() -> list[tuple[dict[str, RecordValue], str | None]]
```
read JSONL records from stdin, one JSON object per line.
if a record contains an 'rkey' field, it is extracted and returned separately.
**Returns:**
* list of (record\_dict, rkey\_or\_none) tuples parsed from JSONL
**Raises:**
* `ValueError`: if JSON parsing fails
### `read_updates_from_stdin`
```python theme={null}
read_updates_from_stdin() -> list[tuple[str, dict[str, RecordValue]]]
```
read JSONL update records from stdin.
each line should be a JSON object with a 'uri' field and update fields.
**Returns:**
* list of (uri, updates\_dict) tuples
**Raises:**
* `ValueError`: if JSON parsing fails or uri field is missing
### `display_batch_result`
```python theme={null}
display_batch_result(result: BatchResult, operation: str = 'deleted') -> None
```
display batch operation results.
**Args:**
* `result`: batch operation result
* `operation`: operation name for display (e.g., "deleted", "updated")
## Classes
### `BatchResult`
result of a batch operation.
**Methods:**
#### `total`
```python theme={null}
total(self) -> int
```
total operations attempted.
#### `success_rate`
```python theme={null}
success_rate(self) -> float
```
success rate as percentage.
