  * Actions Cache client library. Instead we place a limit on the uncompressed
  * size of the overlay-base database.
  *
- * Assuming 2.5:1 compression ratio, the 15 GB limit on uncompressed data would
- * translate to a limit of around 6 GB after compression. This is a high limit
- * compared to the default 10GB Actions Cache capacity, but enforcement of Actions
- * Cache quotas is not immediate.

- * TODO: revisit this limit before removing the restriction for overlay analysis

+ * Assuming 2.5:1 compression ratio, the 7.5 GB limit on uncompressed data would
+ * translate to a limit of around 3 GB after compression.
