MutationsBatcherAsync

MutationsBatcherAsync(
    table: TargetType,
    *,
    flush_interval: float | None = 5,
    flush_limit_mutation_count: int | None = 1000,
    flush_limit_bytes: int = 20971520,
    flow_control_max_mutation_count: int = 100000,
    flow_control_max_bytes: int = 104857600,
    batch_operation_timeout: float | TABLE_DEFAULT = TABLE_DEFAULT.MUTATE_ROWS,
    batch_attempt_timeout: float | None | TABLE_DEFAULT = TABLE_DEFAULT.MUTATE_ROWS,
    batch_retryable_errors: (
        Sequence[type[Exception]] | TABLE_DEFAULT
    ) = TABLE_DEFAULT.MUTATE_ROWS
)

Allows users to send batches using context manager API.

Runs mutate_row, mutate_rows, and check_and_mutate_row internally, combining to use as few network requests as required

Will automatically flush the batcher:

  • every flush_interval seconds
  • after queue size reaches flush_limit_mutation_count
  • after queue reaches flush_limit_bytes
  • when batcher is closed or destroyed
