Compaction Test

Overview

Perform this compaction test to calculate ATSD storage efficiency and estimate disk space requirements for a custom dataset.

Open the Settings > Diagnostics > Compaction page.
Initiate the compaction task. Refresh the page until the task is completed.
Open the Settings > Storage > Database Tables page. Take note of the d table size in the Store File Size (MB) column of the Summary table.
Insert the dataset with a reasonable amount of data, for example 1+ million samples or 50+ megabytes in CSV format.
Execute the compaction again on the Compaction page.
Reload the Database Tables page and calculate the difference in the Store File Size (MB) value.
Multiply the difference by 1048576 and divide it by the total number of samples in the dataset to calculate bytes/sample ratio.

The ratio represents an estimated amount of disk space required to store one time:value sample for the current file system compression codec.
