6. The method of claim 5 , further comprising deleting the data element if the data element was created earlier than the other data elements.
7. The method of claim 1 , wherein the plurality of data elements comprise at least one of an operational feature of the vehicle, a condition of a component of the vehicle and an environmental condition around the vehicle.
8. The method of claim 7 , wherein the one or more of the plurality of data elements are derived from a sensor on the vehicle.
9. The method of claim 1 , further comprising:
detecting that the communications network is available;
transmitting the one or more of the plurality of data elements corresponding to the one or more conditions to the storage platform over the communications network; and
replicating the one or more of the plurality of data elements in the storage platform.
10. The method of claim 9 , further comprising deleting the replicated one or more of the plurality of data elements from the memory region of the event data recorder.
11. The method of claim 10 , further comprising maintaining in the memory region of the event data recorder the plurality of data elements which have not been replicated.
12. The method of claim 1 , further comprising reducing a resolution of the one or more of the plurality of data elements.
13. An apparatus comprising:
in an information processing system comprising one or more vehicles, wherein a given vehicle of the one or more vehicles comprises an event data recorder and a data management module resident in the given vehicle;
at least one processor configured to:
record a plurality of data elements in the event data recorder detect whether a communications network is available for transmission of the plurality of data elements to a storage platform remote from the given vehicle;
detect that the communications network is unavailable for the transmission of the plurality of data elements;
evaluate each of the plurality of data elements to determine which of the plurality of data elements to maintain in a memory region of the event data recorder and which of the plurality of data elements to delete from the memory region of the event data recorder responsive to the detection of the unavailability of the communications network;
use one or more machine learning algorithms to learn one or more conditions leading to one or more vehicle events;
identify an occurrence of the one or more conditions, wherein one or more of the plurality of data elements recorded in the event data recorder correspond to the one or more conditions; and
predict an occurrence of a vehicle event of the one or more vehicle events due to the occurrence of the one or more conditions;
wherein, in evaluating each of the plurality of data elements, the at least one processor is further configured to assign a higher maintenance value to the one or more of the plurality of data elements corresponding to the one or more conditions than to remaining data elements of the plurality of data elements responsive to the predicting.
14. The apparatus of claim 13 , wherein the at least one processor is further configured to delete one or more of the remaining data elements of the plurality of data elements assigned a lower maintenance value than the one or more of the plurality of data elements corresponding to the one or more conditions.
15. An article of manufacture comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processor causes said at least one processor to:
in an information processing system comprising one or more vehicles, wherein a given vehicle of the one or more vehicles comprises an event data recorder and a data management module resident in the given vehicle, record a plurality of data elements in the event data recorder detect whether a communications network is available for transmission of the plurality of data elements to a storage platform remote from the given vehicle;
detect that the communications network is unavailable for the transmission of the plurality of data elements;
evaluate each of the plurality of data elements to determine which of the plurality of data elements to maintain in a memory region of the event data recorder and which of the plurality of data elements to delete from the memory region of the event data recorder responsive to the detection of the unavailability of the communications network;
use one or more machine learning algorithms to learn one or more conditions leading to one or more vehicle events;
identify an occurrence of the one or more conditions, wherein one or more of the plurality of data elements recorded in the event data recorder correspond to the one or more conditions; and
predict an occurrence of a vehicle event of the one or more vehicle events due to the occurrence of the one or more conditions;
wherein, in evaluating each of the plurality of data elements, the program code further causes said at least one processor to assign a higher maintenance value to the one or more of the plurality of data elements corresponding to the one or more conditions than to remaining data elements of the plurality of data elements responsive to the predicting.
16. The article of manufacture of claim 15 , wherein the program code further causes said at least one processor to delete one or more of the remaining data elements of the plurality of data elements assigned a lower maintenance value than the one or more of the plurality of data elements corresponding to the one or more conditions.
