# FLOWPIPE_MAX_CONCURRENCY_HTTP

# FLOWPIPE_MAX_CONCURRENCY_HTTP

Sets the maximum number of `http` step instances that can execute concurrently across all pipeline instances.  When the limit is reached, `http` steps will be queued until enough `http` steps complete to bring the count under the limit. 

The minimum value is `1`, and the default is `500`.

## Usage 


Set the concurrency to 100:
```bash
export FLOWPIPE_MAX_CONCURRENCY_HTTP=100
```

Reset to the default value:
```bash
unset FLOWPIPE_MAX_CONCURRENCY_HTTP
```
