Abstract: Systems and methods are provided for intent tracking asynchronous operations. An example method can include receiving, at a content management system (CMS), a first request to perform an operation on a content item stored at the CMS; adding the request to perform the operation to a queue of operations to be processed by the CMS; and prior to completing the operation: receiving, from a client device associated with a user account registered at the CMS, a second request to access the content item; in response to the second request, determining a predicted state of the content item, the predicted state of the content item reflecting a result of performing the operation on the content item; and providing, to the client device, a response including the predicted state of the content item.

Abstract: Systems and methods for snapshot isolation in a distributed storage system M are provided. In some examples, a method can include receiving a request for data from a data store comprising a plurality of storage nodes, the request comprising a key associated with the data and a request timestamp, identifying a storage node in the plurality of storage nodes from which to read the data based on the key and a mapping of keys to storage nodes, determining that the request is associated with a transaction comprising operations associated with at least one other storage node in the plurality of storage nodes, determining a status of the entry for the key in the key-value table based on a lookup of a transaction table using the transaction identifier, and providing the data when the status of the entry for the key indicates the data is ready to be read.

Abstract: Various embodiments are described herein for methods and systems for managing a parking area. In one embodiment, the method comprises receiving a parking authorization request from a parking lot user, the request specifying a parking stall identifier corresponding to a parking stall occupied by the users vehicle, the request further specifying a parking duration parameter identifying a time duration the user's vehicle can occupy the stall; determining a parking duration rule for the stall based on the parking duration parameter, the rule indicating a parking expiration time; at a first time, receiving a first data associated with the parking stall identifier, the first data comprising an occupancy parameter indicating a presence or absence of a parked vehicle at the identified stall; if the occupancy parameter indicates a presence of a parked vehicle, generate a citation alert for the stall if the first time exceeds the parking expiration time.

Abstract: A system can serialize moves and mounts across namespaces based on lamport clocks. In some examples, the system obtains a request to move a content item from a source namespace to a destination namespace. The system processes an incoming move at the destination and an outgoing move at the source. The system processes for the content item a delete at the source and an add at the destination. The system assigns a first clock to the incoming move and a second clock to the outgoing move, the first clock being lower than the second clock. The system assigns a third clock to the delete and a fourth clock to the add, the third clock being higher than the second clock and lower than the fourth clock. The system serializes the incoming and outgoing moves, the delete and the add based on the first, second, third and fourth clocks.
