Collaboration data proxy system in cloud computing platforms

A computer-implemented method for managing data duplicates in distributed storage systems, the method comprising:

• receiving, at a first node, a request from a requesting second node for a data download comprising a plurality of data chunks in storage of a distributed computing platform, the data chunks cached as corresponding duplicated data chunks on a plurality of nodes in a peer group comprising the first node and the requesting node;
• determining, by the first node and using a metadata table stored in memory of the first node, that a first duplicated data chunk of the duplicated data chunks is available from a peer node of the plurality of nodes in the peer group;
• downloading, by the first node and based on determining that the first duplicated data chunk is available from the peer node, the first duplicated data chunk from the peer node;
• and
• caching the first duplicated data chunk in a cache of the memory of the first node in accordance with a configurable cache strategy specifying an eviction policy for the cache.

One or more computer storage media having computer-executable instructions embodied thereon that, when executed, by one or more processors associated with a first node, causes the one or more processors to perform a method for managing data duplicates in distributed storage systems, the method comprising:

• receiving, at the first node, a request from a requesting second node for a data download comprising a plurality of data chunks in storage of a distributed computing platform, the data chunks cached as corresponding duplicated data chunks on a plurality of nodes in a peer group comprising the first node and the requesting node;
• determining using a metadata table stored in memory of the first node, that a first duplicated data chunk of the duplicated data chunks is available from a peer node of the plurality of nodes in the peer group;
• generating a configuration instance for the request, the configuration instance specifying configuration settings comprising download settings and an in-memory cache mode setting specifying an eviction policy for a cache of the memory of the first node;
• downloading, based on determining that the first duplicated data chunk is available from the peer node, the first duplicated data chunk from the peer node in accordance with the download settings;
• and
• caching the first duplicated data chunk in the cache using the eviction policy for the cache.
