[geomesa-users] Accumulo Key Structure

[Marcel <m.jacob@xxxxxxxxxxx>]

Hello,
I scanned some rows of the deprecated _st_idx table to comprehend the 
index key structure described in the paper.
This results in the following:

structure in paper:
RowID Column Family Column Qualifier
##~geohashPart1(char 1)~datePart1 geohashPart2(char 2-4) 
ident.~geohashPart3(char 5-7)~datePart2

vs.
observed structure:

shardingKey?~???~featureName~geohashPart1(char 1-3)~fullDate 
geohashPart2 (char 4-5) hex-values?
example:
0~0~event~rhe~2014113023 4r 909271fc-44fa-495b-b876-5843df987fef

So obviously the structure has changed. It seems that the date is fully 
encoded in the rowId. Also the number of geohash characters changed. But 
I can´t understand what is stored within the qualifier? Is it only the 
identifier?

Best regards,
Marcel Jacob.
