Deferred index building not idempotent

    XMLWordPrintable

Details

    Description

      I've got some demo scripts that I'm using to create a bunch of deferred indexes and then build them. Running this on a clean system works well, but when I was diagnosing issues and running the script repeatedly, I found that if any indexes already exist in the build index statement, the others are not built.

      i.e.:
      CREATE INDEX def_sourceairport ON `travel-sample`(sourceairport) USING GSI WITH

      {"defer_build":true}

      CREATE INDEX def_name_type ON `travel-sample`(name) WHERE (_type = "User") USING GSI WITH

      {"defer_build":true}

      BUILD INDEX ON `travel-sample`(`def_sourceairport`, `def_name`) USING GSI"

      then
      DROP INDEX `travel-sample`.def_name

      then the same:
      CREATE INDEX def_sourceairport ON `travel-sample`(sourceairport) USING GSI WITH

      {"defer_build":true}

      CREATE INDEX def_name_type ON `travel-sample`(name) WHERE (_type = "User") USING GSI WITH

      {"defer_build":true}

      (fails understandably)
      BUILD INDEX ON `travel-sample`(`def_sourceairport`, `def_name`) USING GSI"
      -this fails saying that def_name is already built, but def_sourceairport does not get built either-
