Do you have some suggestion how can I improve the performance of the
catalogsearch_fulltext indexer for Magento 2.1.X
I already set this indexer to 'Update By Schedule' so only the updated products are refreshed thanks to Mview pattern.
I have ElasticSearch as search engine, but it is not really related to it.
I have around
- 20k products
- 7k products visible in search by store
- 31 stores
- less than 10 new custom searchable attributes
For a full re-index, Magento took around 10 minutes by stores, so around 5 hours for all stores.
I plan to re-index each store in parallel and increase the server CPU and memory because each catalog search index seems independent by stores.
I try to import products with a differential approach, but sometime my customer needs a full product import.
Edit: I did a POC thanks to https://github.com/amphp/parallel reducing from 5 hours to 14 min using the c5.9xlarge EC2 instance with 36vCPU. But I want to know if there is alternative solution. (>1000$ per month)
