Magento 2 Indexer Isolation
===========================

[](#magento-2-indexer-isolation)

Moves slow Magento indexers into their own cron group so they stop blocking everything else.

The problem
-----------

[](#the-problem)

Magento's `index` cron group processes all indexers sequentially. If one takes hours (e.g. `catalogsearch_fulltext` on a large catalogue), every other indexer waits behind it.

What this module does
---------------------

[](#what-this-module-does)

Selected indexers are moved into a separate `index_isolated` cron group that runs in its own PHP process. The remaining indexers continue in the default group unblocked. No additional system crontab entry is needed.

Quick start
-----------

[](#quick-start)

```
cp -r Furan/IndexerIsolation app/code/Furan/IndexerIsolation
bin/magento module:enable Furan_IndexerIsolation
bin/magento setup:upgrade
```

1. Go to Stores > Configuration > Advanced > System > Indexer Isolation
2. Set "Enable Indexer Isolation" to Yes
3. Select which indexers to isolate
4. Save

The multiselect only shows indexers that are safe to isolate. Indexers with a `shared_index` or that other indexers depend on are excluded automatically.

When disabled, Magento behaves exactly as stock. Zero overhead.

How it works
------------

[](#how-it-works)

Two interception layers handle the two indexer pathways:

**Mview (partial reindex via changelogs):** A plugin on `Mview\ConfigInterface` dynamically reassigns the mview group for isolated views from `indexer` to `index_isolated`. The default group skips them, the isolated group picks them up.

**ReindexAllInvalid (full reindex of invalid indexers):** A process-local in-memory flag combined with a plugin on `Indexer\ConfigInterface` filters isolated indexers out of `getIndexers()` during `reindexAllInvalid()`. No database state is modified. The isolated group runs in a separate PHP process and is unaffected by the flag.

Three dedicated cron jobs in the `index_isolated` group handle mview updates, full reindex, and changelog cleanup.

Requirements
------------

[](#requirements)

- Magento 2.4.8 or later
- PHP 8.1+
