-Pig load data with cassandrastorage and slice filter param
Miguel Angel Martin junqu... 2013-07-16, 11:03
I trying to load data from cassandra with slice params option but ther are
no much info about how to use i. I found only a quick reference in
readme.txt in cassandra project .../examples/pig
*Slices on columns can also be specified:*
*grunt> rows = LOAD
*Binary values for slice_start and slice_end can be escaped such as '\u0255'
I want to filter the initial load data by day o range dates and I only
found this info about cassandra and pig
I,m going to try to do a test with dummy data with Composite column
Family like anuniqueIDGenerate:timestamp for example or
anuniqueIDGenerate:stringdate where date is a string with dornat YYY-MM-dd
Another option is use Supercolumn family by day for example ad try to use
slice with this feature
Or another option is create a custom load cassandra but perhaps It´s more
complex and I could this features.
I will appreciate any help or example how I must define cassandra data and
Pig example load with slice.
Thanks in advance and king regards
