Data Import MARC Authorities [Poppy]
- Mykhailo Petryshyn
Overview
In the scope of PERF-698 - Getting issue details... STATUS - * Poppy Release | Data import | Create MARC authority Records it's needed to run tests to answer questions:
- Determine the time it takes to complete Data-import on PCP1 env
- Determine the main modules that are involved in the process (if obvious or if known)
- Test specific settings or items or scenarios:
Check-in and Checkout (CICO) is in progress and there are 5 concurrent users, and run DI for 1K - 5K- 10K-25K-50K
Test concurrent DI jobs with multi-tenants in the same cluster.
Summary
- 1K, 5K, 10K, 50K data import jobs finished successfully without errors or issues. 22K completed with 67 errors, problem in data, because same errors were on 3 tenants.
- General summary. Data Import MARC Authorities work on Poppy like on the previous releases. DI duration is about the same and resource utilization has the same behavior as in the previous releases.
- The environment is stable and can process 5 DI jobs in parallel on 3 tenants.
Test 1. DI Primary tenant 1k-5K-10K-22K-50K
- DI performance for:
- 1K is faster by Orchid but on the same level as Morning Glory and Nolana
- 5K and 10K DI duration is about the same as Orchid, Morning Glory, and Nolana
- 23K and 50K DI duration is longer on Poppy in comparison to Orchid, but faster than on Morning Glory and Nolana
- Resource Utilization during data imports was stable during the test.
- Maximal CPU consumption was for mod-quick-marc service about 55-60% of CPU and spiked up to 80% on mod-data-import-b, when the 50K records file was uploading;
- No memory leaks;
- RDS utilization was about 95%;
- Maximal CPU consumption was for mod-quick-marc service about 55-60% of CPU and spiked up to 80% on mod-data-import-b, when the 50K records file was uploading;
Test 2. DI Primary tenant 1k-5K-10K-22K-50K + CI/CO 5VU
- Average response time is slower from 2 up to 18% for small files(1K, 5K, and 10K ), but for big files (23K, 50K);
- The duration of DI during CICO is similar to results "without CICO";
- Memory and CPU utilization were without problems. The most consuming CPU service is mod-inventory-b about 80%. RDS utilization was about 95%;
Test 3. Multitenant DI 50K-22K-10K-5K-1K
All DI finished successfully(except 23K, DI file has 67 broken records), with no memory leaks.

Service CPU Utilization
CPU Utilization during data-imports was stable during the test, mod-quick-marc-b consumed about 55-60% of CPU and Spikes up to 80% on mod-data-import-b, but we saw the same behavior when large files were uploaded for data-import.
CPU utilization after tests returned to its before-test statements.
Memory utilization
RDS utilization was about 95%
