Test Summary

Reindex could be done in 1 hour 25 minutes (db.r6g.8xlarge) for 10 million instances. It is 6.8 times faster than the Poppy release with db.r6g.xlarge. Duration 2 hours 25 minutes with the db.r6g.xlarge (same database size) and it is 4 times faster compared to Poppy.
It is possible to run reindex with the small-size database (xlarge). duration -- hours and we have 10 mln records
It is not possible to run multitenant reindex. If starting 3 reindex in parallel for 3 tenants from 1 to 3 reindex will fail.
Service CPU utilization was up to 50% for mod-search and 40% for mod-inventory-storage. For all other services CPU did not exceed 20%.
Memory utilization was stable and no memory leaks or OOM issues were observed.
RDS CPU utilization was about 90% for the database db.r6g.xlarge and up to 35% for db.r6g.8xlarge.
A larger database instance type typically results in faster reindexing times. However, for the db.r6g.8xlarge and db.r6g.4xlarge, the reindexing duration is nearly identical. Therefore, for 10 million instance records reindex, it's more efficient to use the db.r6g.4xlarge or db.r6g.2xlarge database instance.

Recommendations & Jiras

It is not possible to run multitenant reindex. If starting 3 reindex in parallel for 3 tenants from 1 to 3 reindex will be failed.

We tested mod-search version 4.0.0-SNAPSHOT.281 with the baseline configuration, and it delivered very good results. However, the database size is quite large (using db.r6g.8xlarge), so we plan to experiment with other types of database instances to explore potential optimizations.

We tested mod-search version 4.0.0-SNAPSHOT.281 with the following increased memory parameters to assess potential performance improvements:

Mem Hard Limit: 4592 MB
Mem Soft Limit: 4480 MB

However, the results showed no significant improvement in performance, indicating that increasing the memory parameters is not beneficial.

mod-search:

4.0.0-SNAPSHOT.278

For this version, we encountered out-of-memory (OOM) issues with mod-search and attempted to resolve them by increasing the memory parameters:

Mem Hard Limit

Mem Soft Limit

: 4480

MB

However, these adjustments did not resolve the issue, so we updated mod-search to version 4.0.0-SNAPSHOT.281.

Data nodes instance scaled down to r6g.large.search

This test was performed to check if it is possible to reindex with regular open search size without scaling it.
It is possible to reindex but it will take longer to reindex (approx 4 times longer for r6g.large.search compared to r6g.4xlarge.search)

2 instances of database db.r6g.xlarge (reader and writer)

The baseline database size, using the db.r6g.8xlarge instance, is quite large. A performance test was conducted to assess whether this size is optimal. The results indicate that it would be more efficient to use smaller instances, such as db.r6g.4xlarge or db.r6g.2xlarge, instead.

Reindex duration and database size correlation:

A larger database instance type typically results in faster reindexing times. However, for the db.r6g.8xlarge and db.r6g.4xlarge, the reindexing duration is nearly identical. Therefore, for 10 million instance records reindex, it's more efficient to use the db.r6g.4xlarge or db.r6g.2xlarge database instance.

2 instances of database database db.r6g.xlarge	2 hours 25 min
