suspend fun dropPrimaryIndex(keyspace: Keyspace, common: CommonOptions = CommonOptions.Default, ignoreIfNotExists: Boolean = false)

Drops an anonymous primary index on keyspace.

suspend fun getAllIndexes(keyspace: Keyspace, common: CommonOptions = CommonOptions.Default): List<QueryIndex>

Returns all indexes from the collection identified by keyspace.

suspend fun getAllIndexes(bucket: String, @SinceCouchbase(value = "7.0") scope: String? = null, @SinceCouchbase(value = "7.0") collection: String? = null, common: CommonOptions = CommonOptions.Default): List<QueryIndex>

Returns all indexes from a bucket, scope, or collection.

suspend fun watchIndexes(keyspace: Keyspace, indexNames: Collection<String>, includePrimary: Boolean = false, timeout: Duration, common: CommonOptions = CommonOptions.Default)

Returns when the indexes named indexNames in keyspace are online.
