Reindexing
...
1 (10/50 Partitions)
Indexing Data Rate graph 1 shows a spike of up to 126K/min for about 9 hours, then it tailed off for another 6+ hours
...
Indexing Data Rate graph 2 shows the tail end of the reindexing where the indexing rate drops to below 5K/min and drags out until 19:00.

Service CPU Utilization (Reindexing 10/50 Partitions)
The main services, mod-inventory-storage and mod-search, doesn't show much if any activity after 12:30 (and through 19:00) when the indexing rate dropped to a few operations/min from 60K+/min
Database CPU Utilization (Reindexing 10/50 Partitions)
The database CPU utilization graph also shows the same story. Note that the time here is +5 UTC
MSK Cluster CPU Utilizations (Reindexing 10/50 Partitions)
Not much happening, only a bump in the CPU for the entire duration after the initial short-lived spikes.
OpenSearch Graphs (Reindexing 2 w/2 Partitions)
Comparing to Reindexing 1 which there had been 10/50 partitions each, reindexing 2 with topics having 2 partitions had a shorter burst of a high rate of indexing, between 32K and 65K operations per minute, but even then this number is about half of Reindexing 1 (between 64K and 120K). The initial high rate burst lasted for about 4 hours compared to 9 hours and the long tail of lower indexing rate is about 8 hours long compared to 6.5 hours in Reindexing 1.
Service CPU Utilization (Reindexing 2 w/2 Partitions)
Service CPU utilization is also lowered for mod-search and mod-inventory-storage (well below 50%) compared to reindexing 1 (around 30%-50%)
Database CPU Utilization (Reindexing 2 w/2 Partitions)
Database CPU Utilization is also lowered in reindexing 2 during the initial 4 hours spikes, to about 5% on average compared to 10-13% average in reindexing 1
MSK Cluster CPU Utilizations (Reindexing 2 w/2 Partitions)
MSK cluster CPU Utilization graph also doesn't show a noticeable bump in utilization during te initial 4 hours burst.
OpenSearch Graphs (Reindexing 3 w/2 Partitions)
Service CPU Utilization (Reindexing 3 w/2 Partitions)
Reindexing 3 with all topics having 2 partitions have the same indexing rate pattern as Reindexing 2 with the initial high rate burst lasted for about 4 hours and a 7 hours tail end.
Reindexing 3's service CPU utilization graph also shows the same behavior as in Reindexing 2 with the main modules' CPU utilization is well less than 505.
Database CPU Utilization (Reindexing 3 w/2 Partitions)
Reindexing 3's DB CPU utilization graph also shows the same behavior as in Reindexing 2 with the DB CPU utilization around 7%..
MSK Cluster CPU Utilization (Reindexing 3 w/2 Partitions)
Reindexing 3's service MSK Cluster utilization graph also shows the same behavior as in Reindexing 2 with a little bump throughout the reindexing.
