Dear CarbonData Developers,
There is an ongoing effort amongst the SQL engines of the Hadoop stack
to support different timestamp semantics. This development has some
implications for the low-level timestamp types as well. The new
timestamp types added to the different SQL engines will rely on the
decisions of the lower level components about which timestamps
semantics they support and how.
I have created a document to summarize what this means for on-disk
storage formats in general and I am sending it out to multiple dev
mailing lists to let you know about this new requirement and to
initiate a discussion in affected open source components.
The document can be read here:

Thanks,
