ajayaadukhlov, Do we have plans for LSI to be implemented some other way?11:10
*** ajayaa has quit IRC11:17

dukhlovyes11:35
dukhlovI wrote custom cassandra local secondary implementation PoC11:36
dukhlovhttps://review.openstack.org/#/c/107500/11:36
dukhlovif we inject this library to cassandra classpath we can execute CREATE CUSTOM INDEX ... query11:39
dukhlovand then use it11:39
*** ajayaa has joined #magnetodb11:40
dukhlovalso we need to adapt our cassandra storage driver to generate new queries11:40
ajayaadukhlov, what kind of new queries are we talking about?12:05
ajayaaand also do you plan to implement  LSI in some other way?12:05
dukhlovnow we create batch of inserts if we need to insert single row12:08
dukhlovone for original row and a few for index rows12:08
dukhlovif we use cassandra native LSI support we will only execute query with insert of original row12:09
dukhlovalso it is required to thenge queries for querying rows by local secondary indices12:11
dukhlovI mean that we need to change CQL queries to execute the same MagnetoDB queries12:11
dukhlovand also do you plan to implement  LSI in some other way?12:12
dukhlovWhat have you meant?12:12
dukhlovI have already answered, yes  I plan to replace current solution based on LSI emulation by using CUSTOM cassandra native secondary indices12:14
