2 partitions
| failed | failed |
With an increase in the number of partitions, there is no noticeable change in the performance of the service, however, negative trends were observed - an increase in the number of errors, more often the data import procedures fell.
number of partitions - 2
this table shows the results of a group of sequential data import tests for 2 partitions. In the case of errors, the number of missing entities in the database was determined
