Subject How are Phoenix Arrays Stored in HBase?
Date Fri, 19 Oct 2018 21:40:48 GMT
Hi,

Sorry if this is too basic of a question. I tried to look through the
documentation but could not find the information. How are Phoenix Arrays
stored in HBase, and in particular, how are varchar array stored?

I tried to upsert data in phoenix, and compare the HBase value:

'0' *0*\x00\x00\x00\x80\x01\x00\x00\x00\x04\x00\x00\x00\x01\x01
'0', '0' 0\x000\x00\x00\x00\x80\x01\x80\x03\x00\x00\x00\x06\x00\x00\x00\x02
\x01
'1', '1' 1\x001\x00\x00\x00\x80\x01\x80\x03\x00\x00\x00\x06\x00\x00\x00\x02
\x01
'1', '23' 1\x0023\x00\x00\x00\x80\x01\x80\x03\x00\x00\x00\x07\x00\x00\x00
\x02\x01
[''] \x00\x00\x80\x01\x00\x00\x00\x02\x00\x00\x00\x01\x01
['', ''] \x00\x00\x80\x01\x80\x01\x00\x00\x00\x02\x00\x00\x00\x02\x01

I was able to deduce that the varchar is stored with a zero byte
terminator, and I think there is another part tracking how many items are
in an array, but I could not quite figure out the array information in hex
that follows... Can someone help me understand how the array is stored in
HBase?

Thank you!
