Hi Selva, Oh my bad, thanks for confirming this. It help me discover that the reason I was confused was that in one of my test case, the first byte was x20, ASCII for space. And I did not pay attention to the space, offsetting all records by one byte, making it impossible to make sense... Eric

Hi Eric, What gets stored in hbase should be the straight dump of aligned format as explained in exp/ExpAlignedFormat.h.

Hi Trafodioneers, I have been experimenting with align format and what get stored in Hbase. It is clearly not a straight dump of align format as it flows in tupples and decribed in exp/ExpAlignedFormat.h. So I am thinking there must be in the code a disk (hbase) serialization/deserialization from and to tupple align format. Any clue what file would deal with that?

Hi Trafodioneers, I have been looking, with no success so far, where I can find for a particular column, its corresponding fixed length or variable length offset location on an align format record, along with the null bit index corresponding for the case of nullable columns. Was thinking I’ll find this in NAColumn, or NAType may be? But no luck so far. Anyone knows where I can find that? Thanks, Eric
