Composite Columns Key Retrieval about perlcassa

[mkjellman]

Could you post a cf schema that your looking to query just to make sure i totally understand the request? Thanks

Let's suppose i want to retrieve a row with this key:

RowKey: 2009-04-19 22:40:25-0900:smtp.usma.bluenet.:10.1.60.25:A:167853061:667da0075b5a14c65eff0b25308cf072
=> (column=answer, value=10.1.60.25, timestamp=1359759908728109)
....

The row key is made from multiple columns (date, query, answer, type, dst_ip, checksum)
the Column Family in this case is defined as:

CREATE COLUMN FAMILY dns WITH comparator = 'UTF8Type'
AND key_validation_class = 'CompositeType(DateType, UTF8Type, UTF8Type, UTF8Type, DecimalType, UTF8Type)'
AND compression_options = {sstable_compression: SnappyCompressor} and column_metadata = [
{column_name: src_ip, validation_class: DecimalType},
{column_name: dst_ip, validation_class: DecimalType},
{column_name: query, validation_class: UTF8Type},
{column_name: type, validation_class: UTF8Type},
{column_name: answer, validation_class: UTF8Type},
{column_name: rr_class, validation_class: UTF8Type},
{column_name: date, validation_class: DateType},
{column_name: checksum, validation_class: UTF8Type}
];

As described, how would i fetch an specific row using perlcassa?

[mkjellman]

honestly, I never thought of using a CompositeType in a key. I assume your just doing that to validate your input for the key name?

Should be pretty easy for me to add in though.

It would be AWESOME if you can add support for it :)

@mkjellman Do you still plan to implement this, and if so, any idea when you might get to it?

[mkjellman]

@dmcnelis apologies on the delay. i'll try to get something committed into trunk todayish

[dmcnelis]

Awesomeness!

Hi ... this would be great..can you also add support for row key as long data type ..i have also added my issue separately
