as part of development of streamparse, have batchingbolt processes tuples in batches. it's intended use things databases more performant when send things in batches. i've proposed switching our batchingbolt implementation on using timer/thread approach using tick tuples; however, 1 of fellow devs pointed out our current approach final batch processed when topology shutdown (and it's in inactive state), whereas isn't explicitly documented anywhere tick tuples. therefore, question this: storm continue sending tick tuples bolts after kill/deactivate has been issued, while in waiting/inactive period? topology lifecycle docs don't make clear. http://mail-archives.apache.org/mod_mbox/storm-user/201506.mbox/%3ccaf5108ijgpdmeax1lakq1mg6mszqf=ym=vo8aacmn0ruinfnkq@mail.gmail.com%3e afaik, "setup-tick!" called start of executor (which schedules tick timer each executor), , tick tuples emitted unless worker going shutdown. in short, fellow cor...

i've been working whit saml extension connect adfs server. i've hacked sample application use adfs server , went well, know if there way connect idp without using loging page of idp. mean if there way process in background end-user. thinking doing query adfs or users , authentication sp login page, avoiding need user authenticate in idp login page. thank much. appreciate on that the purpose of federated authentication delegate centralized server in such way relaying parties/service providers not have access user's credentials. enabling authentication directly in application violate principle , reason not supported neither spring saml nor adfs. if want authenticate users directly, use authentication directly against active directory instead of adfs. support use-case.

i have table items has field priority . half of elements in field priority have unique value ranging 1 x . want elements field priority null have incremental values of x+1 y . i have tried update items set priority = ifnull(priority, 0) but not want. want non null fields stay is, achieved following: set priority = ifnull(priority, 0) and null fields start being incremented value, following: select max(priority) items; so thing comes mind close to update items set priority = ifnull(priority, 0) + (select max(priority) items) priority null however not sure how go doing so. hints or tips? you can current maximum priority , store in variable. then, bring value query, using cross join . can increment value in set statement: update items cross join (select @x := max(priority) items) maxp set priority = (@x := @x + 1) priority null;

i have 2 columns called major , minor trying greater , less queries on. represent versions. version 2.1, 2 in major column , 1 minor column. how can these queries? avoid creating new column. the issue if query model.where('major > ? , minor > ?', 3, 4) , won't 4.1 or 5.2 because minor less 4. i using rails 3.2 , ruby 1.9. also, versions don't complicated number.number (ex. 2.9 or 4.3) lets assume in style. i think correct sql query follows: major > :major -- check bigger major or (major = :major , minor > :minor) -- check within same major you can use in activerecord right placeholder conditions, though should remove comments (the parts of line after -- ). example: myproductwithversion.where('major > :major or (major = :major , minor > :minor)', major: 2, minor: 1)
