Re: Considering lossy encoding/compression?

Hi,


I think it's good to support lossy encoding method as some companies want it,
and there are more lossy encoding methods in paper, it is also a good
work to implement them to improve system performance.


Thanks,

Hi,

&gt; I know PI has Spinning Door Transformation compress algorithm which is a
lossy encoding method, and it has been used in many cement factories.

Yes, if we have demand to implement a lossy encoding, I'd like to also
choose SDT...

&gt; Hi,
&gt;
&gt; Now IoTDB only supports lossless encoding method, like RLE, delta-of-delta,
&gt; etc..
&gt;
&gt; I'd like to know is there a requirement that using a lossy encoding method
&gt; for storing IoT data?
&gt;
&gt; If so, we can add some lossy encoding options.
&gt;
