Cache eviction during off-peak transactions

1. A method comprising:

monitoring, by a computing device, request activity for content stored in a content cache;

identifying, by the computing device based on the monitoring, a high request activity time period and a low request activity time period for the monitored request activity, the high request activity time period corresponding to a high request activity level and the low request activity time period corresponding to a low request activity level;

selecting, by the computing device, a future time period during which a request activity level is anticipated to be at least as high as the high request activity level;

allocating, by the computing device for the selected future time period, an amount of cache space at least as great as an amount of cache space used during the selected high request activity time period; and

causing, by the computing device, the content to be cached in the allocated amount of cache space during the future time period.

2. The method of claim 1 , further comprising, adjusting the allocated amount of cache space for the future time period based on past request activity data.

3. The method of claim 2 , wherein, the past request activity data relates to request activity data from a geographically located time zone that precedes the time zone of the future time period.

4. The method of claim 1 , wherein, allocating the at least as great as an amount of cache space comprises evicting older content stored in the content cache during the selected low request activity time period.

5. The method of claim 4 , wherein the evicting of the older content stored in the content cache is performed at a predetermined time prior to a start of the high request activity time period.

6. The method of claim 1 , wherein, allocating the at least as great as an amount of cache space comprises evicting multiple versions of the same content stored in the content cache.

7. The method of claim 6 , wherein, the multiple versions include the same content correlated for different geographical time zones.

8. The method of claim 6 , wherein, the multiple versions include the same content in standard definition (SD) and in high definition (HD).

9. The method of claim 1 , wherein, the content stored in the content cache is a plurality of episodes of a same series.

10. The method of claim 9 , wherein, the monitoring the request activity for content stored in a content cache includes monitoring the plurality of episodes of the same series to determine whether the episodes have a high request activity or a low request activity.

11. The method of claim 9 , wherein, the high request activity time period is a time period for which the amount of request activity for content stored in a content cache is above a threshold amount.

12. The method of claim 9 , wherein, the low request activity time period is a time period for which the amount of request activity for content stored in a content cache is below a threshold amount.

13. An apparatus comprising:

one or more processors; and

memory storing computer-executable instructions that, when executed by the one or more processors, cause the apparatus to:

monitor, by a computing device, request activity for content stored in a content cache;

identify, by the computing device based on the monitoring, a high request activity time period and a low request activity time period for the monitored request activity, the high request activity time period corresponding to a high request activity level and the low request activity time period corresponding to a low request activity level;

select, by the computing device, a future time period during which a request activity level is anticipated to be at least as high as the high request activity level;

allocate, by the computing device for the selected future time period, an amount of cache space at least as great as an amount of cache space used during the selected high request activity time period; and

cause, by the computing device, the content to be cached in the allocated amount of cache space during the future time period.

14. The apparatus of claim 13 , further comprising, adjusting the allocated amount of cache space for the future time period based on past request activity data.

15. The apparatus of claim 14 , wherein, the past request activity data relates to request activity data from a geographically located time zone that precedes the time zone of the future time period.

16. The apparatus of claim 13 , wherein, allocating the at least as great as an amount of cache space comprises evicting older content stored in the content cache during the selected low request activity time period.

17. The apparatus of claim 16 , wherein the evicting of the older content stored in the content cache is performed at a predetermined time prior to a start of the high request activity time period.

18. The apparatus of claim 13 , wherein, allocating the at least as great as an amount of cache space comprises evicting multiple versions of the same content stored in the content cache.

19. The apparatus of claim 13 , wherein, the content stored in the content cache is a plurality of episodes of a same series.

20. The apparatus of claim 19 , wherein, the monitoring the request activity for content stored in a content cache includes monitoring the plurality of episodes of the same series to determine whether the episodes have a high request activity or a low request activity, wherein the high request activity is a request that is above a threshold amount and the low request activity is a request that is below the threshold amount.
