OpenSolr Turbo Indexer

True Parallel Solr Indexing for Drupal 9 / 10 / 11

Typical Workflow

Complete workflow for re-indexing all content on a specific server: 

# 1. Rebuild trackers for all indexes on the server
drush osrb --server=my_solr_server

# 2. Start parallel indexing
drush ost --server=my_solr_server --workers=10 --batch=500 --background

# 3. Monitor progress
drush oss

# 4. Watch detailed log (optional)
tail -f /tmp/opensolr_turbo.log

Step-by-Step Guide

Step 1: Check Current Status

Before starting, see what needs to be indexed:

drush oss

This shows you:

Step 2: Rebuild Trackers (If Needed)

If the tracker is out of sync or you want to re-index everything from scratch: 

drush osrb --server=my_solr_server

This marks all items as "needs indexing" by re-scanning all content.

Step 3: Start Indexing

For long jobs, use background mode:

drush ost --server=my_solr_server --workers=8 --batch=500 --background
💡 Choosing Workers and Batch Size
  • Workers: Start with your CPU count, adjust based on load
  • Batch: 500 is good for most sites; reduce if you have complex content

Step 4: Monitor Progress

Check progress periodically:

# Quick status check
drush oss

# Detailed live log
tail -f /tmp/opensolr_turbo.log

Step 5: Verify Completion

When done, verify everything is indexed:

drush oss

All indexes should show 100% with 0 remaining items.

Quick Re-index

For a quick interactive re-index (small sites or testing):

# Stay in foreground, see live progress
drush ost --workers=4 --batch=100

Single Index

To index just one specific index:

drush osrb --index=my_solr_index
drush ost --index=my_solr_index --workers=4 --batch=500
