ManageIndices

Creates/Drops an index in a target bucket in Couchbase.

インデックスの構築

匿名のプライマリインデックスはこれらのパラメータで作成できます。

EXECUTE ManageIndices
  @BucketName = 'Players'
  @Action = 'CREATE'
  @IsPrimary = 'true'
  @IndexType = 'VIEW'

これは、このN1QL を実行することと同じです。

CREATE PRIMARY INDEX ON `Players` USING VIEW

上記のパラメータに加えて、@Name を指定することで名前付きプライマリインデックスを作成できます。

EXECUTE ManageIndices
  @BucketName = 'Players'
  @Action = 'CREATE'
  @IsPrimary = 'true'
  @Name = 'Players_primary'
  @IndexType = 'VIEW'

セカンダリインデックスは、@IsPrimary をfalse に設定して、少なくとも1つの式を指定することで作成できます。

EXECUTE ManageIndices
  @BucketName = 'Players',
  @Action = 'CREATE',
  @IsPrimary = 'false',
  @Name = 'Players_playtime_score',
  @Expressions = '["score", "playtime"]'

これは、次のN1QL を実行することと同じです。

CREATE INDEX `Players_playtime_score` ON `Players`(score, playtime) USING GSI;

複数のノードとフィルタを指定して、より複雑なインデックスを生成することもできます。They must be provided as JSON lists:

EXECUTE ManageIndices
  @BucketName = 'Players',
  @Name = 'TopPlayers',
  @Expressions = '["score", "playtime"]',
  @Filter = '["topscore > 1000", "playtime > 600"]',
  @Nodes = '["127.0.0.1:8091", "192.168.0.100:8091"]'

これは、次のN1QL を実行することと同じです。

CREATE INDEX `TopPlayers` ON `Players`(score, playtime) WHERE topscore > 1000 AND playtime > 600 USING GSI WITH { "nodes": ["127.0.0.1:8091", "192.168.0.100:8091"]};
