Subject Re: Numbers low-level format in Phoenix
Date Thu, 08 Jan 2015 11:09:14 GMT
Hi Lavrenty,

Phoenix actually does store numerical data using byte arrays, in a
similar fashion to what the HBase bytes class does. There's more
information on the various types and their underlying encoding
available here:

I'm guessing you got the string representation
("\x00\x00\x00\x00I\x96\x02\xD2") from the HBase shell -- this is a
string representation of the byte array (containing 8 bytes)
containing the serialized value of 1234567890. The strings you posted
like "[B@13217cf6" are the default string representation of byte
arrays in java. To convert these to a human-readable value (like what
the HBase shell does), you could do the following:
