DATA CACHING IN A COLLABORATIVE FILE SHARING SYSTEM

摘要

A system and method for facilitating cache alignment in a cross-enterprise file collaboration system. The example method includes maintaining a plurality of messages in a cache, each message associated with a message offset; determining a message batch size; receiving a first request for a message characterized by a first offset; responding to the first request at least in part by sending an amount of data equal to the batch size starting at the first offset; receiving a second request for a second message of characterized by a second offset; and if the second offset plus the data batch size spans across a boundary determined by the first offset plus the data batch size, then responding to the second request by sending an amount of data equal to the first offset plus the data batch size minus the second offset. In a more specific embodiment, the first and second requests are received from different committers.

1. A method for maintaining alignment in a cache, the cache used for distributing log information in a cross-enterprise file collaboration system, the method comprising the following performed by one or more server computers:
maintaining a plurality of messages in a cache, each message associated with a topic partition and a message offset; determining a message batch size; receiving a first request for a message characterized by a first offset; responding to the first request at least in part by sending an amount of data equal to the batch size starting at the first offset; receiving a second request for a second message characterized by a second offset; wherein if the second offset plus the data batch size spans across a boundary determined by the first offset plus the data batch size then responding to the second request by sending an amount of data equal to the first offset plus the data batch size minus the second offset.
