Hi, Is there a way for a client to issue an advisory prefetch request to a server? The scenario I have in mind is: 1. The client knows it will need to access a specific part of the file but it will take it a while to plow through, with many small read requests. 2. It suspects (or knows) it is actually talking to a proxy server that needs to fetch data over WAN. 3. It knows it will NOT need any other part of the file. The request would be ignored by normal (non-proxy) servers. The use case is populating proxy-cache with known missing blocks from hadoop, 64 or 128MB in size ... but doing it on demand, when the "broken" file is actually accessed, and still trying to minimize latency in retrieval. Cheers, Matevz ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-DEV list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-DEV&A=1
