Thus, the two user-defined functions included in +storage.sql. MySQL doesn't kill a transaction when a duplicate is detected, but +PostgreSQL does. So, to preserve the workflow, I included the two functions +which trap this error and allow the code to continue executing. The only other +change I made was to fully translate the MySQL queries to PostgreSQL compatible ones +and tidy up some of the extant tree storage code. + +storage_unsafe.sql really isn't unsafe, but I have pulled some of the safety +rails from the tables to improve performance. It also works under the notion that +there will only be a single tree in a given database. An improvement on this theme +would be to add all layers below the trees table in their own separate schemas. +This would further eliminate indexs and foreign key requirements, but it should +be left for those who require enhanced performance. diff --git a/storage/postgres/log_storage.go b/storage/postgres/log_storage.go new file mode 100644 index 0000000000..a0891a3d1e --- /dev/null +++ b/storage/postgres/log_storage.go @@ -0,0 +1,1010 @@ +// Copyright 2016 Google Inc.
