vivekdhello isviridov11:52
vivekdi'm looking at the item updates based on conditions in dynamodb @ https://wiki.openstack.org/wiki/MagnetoDB/specs/data-api#Request_Parameters_411:52
vivekdand i'm trying to find which of those is supported in magnetodb by looking @ https://wiki.openstack.org/wiki/MagnetoDB/specs/data-api#Request_Parameters_411:52
vivekdbut the page doesn't contain complete information about the supported conditional expressions11:53
vivekdit would be nice if you can point me to documentation in this regard11:53
isviridovvivekd : hello11:53
vivekdoops the dynamodb link is http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.SpecifyingConditions.html11:53
isviridovvivekd : the most actual documentation is here http://magnetodb.readthedocs.org/en/latest/put_item.html, but it is the same11:55
vivekdisviridov: yes i already saw that link11:56
vivekdisviridov: does that mean only "exists" conditional is supported at the moment in magnetodb?11:59
isviridovThere are two supported for now.12:05
isviridovexists and value12:05

*** k4n0 has quit IRC12:28
vivekdisviridov: thanks for the meticulous pointer.12:38
vivekdif i understood the code right, expected conditions support only three types of conditions - EQUAL, NULL, NOT_NULL12:39
vivekdand these map to the dynamodb condition types - "=", "attribute_exists", "attribute_not_exists"12:39
vivekdisviridov: is there any plan to support the rest of the condition types @ http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.SpecifyingConditions.html ?12:39
dukhlovthis feature is implemented using Cassandra CAS operations12:40
dukhlovfor now only  '=' is supported12:41
dukhlovif such feature appears in cassandra we will add it to MagnetoDB12:42
isviridovvivekd : not yet12:42
vivekdoh ok dukhlov / isviridov12:46
vivekddukhlov: i searched through the cassandra issues to see13:25
vivekdif cassandra plans to implement such a feature https://issues.apache.org/jira/browse/ACCUMULO-1000?jql=text%20~%20%22compare%20and%20set%2213:25
vivekdbut i couldn't find any13:25
vivekdisviridov / dukhlov : do you know if cassandra has plans to support such a feature ?13:26
dukhlovI don't know. I guess the best way is to ask in cassandra IRC channel13:27
isviridovvivekd : I don't have such info13:27
dukhlovand anyway create jira ticket13:28
vivekdok thank you isviridov / dukhlov13:28
