Annotation Type SqlBatch

@Retention(RUNTIME) @Target(METHOD) public @interface SqlBatch
Annotate a method to indicate that it will create and execute a SQL batch. At least one bound argument must be an Iterator or Iterable, values from this will be taken and applied to each row of the batch. Non iterable bound arguments will be treated as constant values and bound to each row.

Unfortunately, because of how batches work, statement customizers and sql statement customizers which affect SQL generation will *not* work with batches. This primarily effects statement location and rewriting, which will always use the values defined on the bound Handle.

If you want to chunk up the logical batch into a number of smaller batches (say around 1000 rows at a time in order to not wreck havoc on the transaction log, you should see BatchChunkSize
