Hi,
Recently, we realized that the Gorilla encoding algorithm that has been used
inside IoTDB may have some issues, because it will cause time series data (the
value part) to become more space-consuming after encoding. This is not in line
with expectations. Usually after using Gorilla encoding,
Hi,
Nice!
One question. So, if we reimplement the Gorilla algorithm, how to consider
the version compatibility?
1. Upgrade the TsFile version to 03, or
2. Add a new encoding name to the corrected gorilla.
Best,

Hi,
Maintaining two versions of gorilla encoding is ok.
Could we change the default time encoding from TS2_DIFF to Gorilla and keep
compatible?
Thanks,

Hi,
+1 for version number :)

Hi,
Version number +1
When I was doing the tsfile upgrading module
sed on Michael's implementation and name the two
encodings TS2_DIFF_V1 and TS2_DIFF_V2.
