What metrics did you use to evaluate the level of database fill in your last project?

The following metrics are usually used to assess the degree of database fill in a project:

• Data volume: how much data is stored in the database (in megabytes, gigabytes).
• Percentage of allocated space used: how full the tables and indexes are relative to the allocated disk space.
• Number of records in key tables: helps understand the load and data growth.
• Data fragmentation: affects performance and storage efficiency.
• Data growth trends over time: fill trends for scaling planning.

In Java projects, database monitoring tools or queries to system tables can be used to obtain these metrics.
