These are binary blobs used by Fusion to extend or customize the behavior of query processing stages.
ConfigSync specifically manages these plugins to ensure they’re correctly integrated into Fusion.

<LwTemplate />

Check out the [Query Stage SDK](/docs/5/fusion/dev-portal/query-stage-sdk/overview) for details on how these plugins work.

You’ll store these plugins in `_lw_system/query-stage-plugins` within your repo.
This special folder is where ConfigSync looks to manage and synchronize query stage plugins.
