<div dir="ltr"><div>So I am trying to come up with a good, simple binary file-format that works well with 'Big Data' platforms like Hadoop, Spark, and S3 (see issue <a href="https://github.com/scifio/scifio/issues/265">https://github.com/scifio/scifio/issues/265</a>). The idea is to keep the storage as simple as possible and the first implementation of such a format is shown here</div><div><a href="https://github.com/thunder-project/thunder/tree/master/python/thunder/utils/data/fish/series">https://github.com/thunder-project/thunder/tree/master/python/thunder/utils/data/fish/series</a><br></div><div>It consists of the binary file accompanied by a conf.json file with the following contents</div><div><pre style="color:rgb(0,0,0)">{
"valuetype": "uint8",
"nkeys": 3,
"keytype": "int16",
"dims": [
76,
87,
2
],
"nvalues": 240,
"input": "key02_00000-key01_00000-key00_00000.bin"
}</pre></div><div>Since Big Data platforms normally work with key-value pairs the idea would be to have a key consisting of several numbers (nkeys) of type (keytype) and then a value as an array of type (valuetype) with dimensions (dims) and all of this spread into multiple files so they can be easily written and read in parallel (or on different machines to a shared file system).</div><div><br></div><div>Does anyone have any suggestions for making a simple format around this? The best case would be to have something that could be easily read into or written from ImageJ, Matlab, Python, or whatever other tool is around with just a few lines of code and no dependencies.</div><div><br></div><div>Thanks</div><div>Kevin</div><br clear="all"><div><br></div>-- <br><div class="gmail_signature">----<br>Kevin Mader<br>Mobile : +41 (0)78 755 14 38<br>Office (PSI) : +41 (0)56 310 58 53<br>Office (ETH) : +41 (0)44 633 61 86<br>Home : +1 (503) 610-8754<br>WBBA 213<br>5232 Villigen PSI</div>
