Abstract
Systems and methods for managing an index shared by a plurality of processes. One method includes reading, with a process, the index at a first state and maintaining a journal of operations to be performed on the index at the first state by the process. Each operation included in the journal includes a create operation or a delete operation. The method also includes, in response to a predetermined event, applying the journal of the one of the plurality of processes to update the index. Applying the journal includes deleting an existing entry from the index and adding a new entry to the index for each create operation included in the journal specifying a key included in an entry of the index at the second state, and ignoring each delete operation included in the journal specifying a key not included in an entry of the index at the second state.
