Changed the multi-shard utility hook to always run (consistency\n       with router executor hook, removes ad-hoc \"installed\" boolean)\n\n    2. Change the global connection list in multi_shard_transaction to\n       instead be a hash; update related functions to operate on global\n       hash instead of local hash/global list\n\n    3. Remove check within DDL code to prevent subsequent DDL commands;\n       place unset/reset guard around call to ConnectToNode to permit\n       connecting to additional nodes after DDL transaction has begun\n\nIn addition, code has been added to raise an error if a ROLLBACK TO\nSAVEPOINT is attempted (similar to router executor), and comprehensive\ntests execute all multi-DDL scenarios (full success, user ROLLBACK, any\nactual errors (say, duplicate index), partial failure (duplicate index\non one node but not others), partial COMMIT (one node fails), and 2PC\npartial PREPARE (one node fails)). Interleavings with other commands\n(DML, \\copy) are similarly all covered.","distinct":true,"url":"https://api.github.com/repos/citusdata/citus/commits/74f4e0003b7c29cbbeea27fb362eb6c68ea81097"},{"sha":"9fd6dafe33088f36c665e060bad1bb71874a9234","author":{"name":"Jason Petersen","email":"04931595d517c351b4941bf90024e5b85dd51408@gmail.com"},"message":"Merge pull request #764 from citusdata/feature/allow_multi_ddl_xact_block\n\nPermit multiple DDL commands in a transaction\r\n\r\ncr: @marcocitus","distinct":true,"url":"https://api.github.com/repos/citusdata/citus/commits/9fd6dafe33088f36c665e060bad1bb71874a9234"}]}
