Interface CloudSpannerJdbcStatement (2.25.1)

This interface is implemented by Statements that are created on Cloud Spanner JDBC connections.

Partitions the given query, so it can be executed in parallel. This method returns a ResultSet with a string-representation of the partitions that were created. These strings can be used to execute a partition either on this connection or an any other connection (on this host or an any other host) by calling the method #runPartition(String). This method will automatically enable data boost for the query if CloudSpannerJdbcConnection#isDataBoostEnabled() returns true.

Executes the given partition of a query. The encodedPartitionId should be a string that was returned by #partitionQuery(String, PartitionOptions, QueryOption...).

Executes the given query as a partitioned query. The query will first be partitioned using the #partitionQuery(String, PartitionOptions, QueryOption...) method. Each of the partitions will then be executed in the background, and the results will be merged into a single result set.

This method will use CloudSpannerJdbcConnection#getMaxPartitionedParallelism() threads to execute the partitioned query. Set this variable to a higher/lower value to increase/decrease the degree of parallelism used for execution.
