A mechanism is provided in a data processing system comprising at least one processor and at least one memory. The at least one memory comprise instructions which are executed by the at least one processor and configure the processor to implement a read-ahead manager for adaptive read-ahead in log structured storage. The read-ahead manager determines a probability value P representing a probability to read into cache a temporal environment for a front-end read for a given segment in user space in a log structured storage. Responsive to performing a front-end read of a record of the given segment in the log structured storage, the read-ahead manager performs pre-fetch of the temporal environment for the record with probability P.
