I also added the maintainers for sharding to the thread. May be giving a bit of detail about access pattern w.r.t. number of mounts that are used for writing/reading would be helpful. I am assuming write-once and multiple concurrent reads means that Reads will not happen until the file is completely written to. Could you explain a bit more about the workload?<br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div><br></div><div>Thanks</div><div>Ashayam Gupta</div></div></div></div>
