Batch Size

Estimate Calls

Batching turns many small operations into fewer grouped operations. A simple arithmetic estimate helps choose a batch size before running expensive commands.

Program

Play the script to choose the item count and see the estimated number of batches.

batch_size_plan.sh 
#!/usr/bin/env bash

items=
batch_size=4
batches=$(((items + batch_size - 1) / batch_size))
echo "items=$items batch=$batch_size batches=$batches"

#!/usr/bin/env bash

items=
batch_size=4
batches=$(((items + batch_size - 1) / batch_size))
echo "items=$items batch=$batch_size batches=$batches"
batch size A batch size controls how many items each grouped operation handles.
ceiling division Adding `batch_size - 1` before division rounds up partial batches.
call estimate Estimating calls helps reason about cost before running work.
