| * + " k int PRIMARY KEY," |
| * + " v1 text," |
| * + " v2 int," |
| * + " v3 myType," |
| * + ")"; |
| * String insert = "INSERT INTO myKs.myTable (k, v1, v2, v3) VALUES (?, ?, ?, ?)"; |
| * |
| * // Creates a new writer. You need to provide at least the directory where to write the created sstable, |
| * // the schema for the sstable to write and a (prepared) modification statement to use. If you do not use the |
| * // default partitioner (Murmur3Partitioner), you will also need to provide the partitioner in use, see |
| * // CQLSSTableWriter.Builder for more details on the available options. |
| * CQLSSTableWriter writer = CQLSSTableWriter.builder() |
| * .inDirectory("path/to/directory") |
| * .withType(type) |
| * .forTable(schema) |
| * .using(insert).build(); |
| * |
| * UserType myType = writer.getUDType("myType"); |
| * // Adds a nember of rows to the resulting sstable |
| * writer.addRow(0, "test1", 24, myType.newValue().setInt("a", 10).setInt("b", 20)); |
| * writer.addRow(1, "test2", null, null); |
| * writer.addRow(2, "test3", 42, myType.newValue().setInt("a", 30).setInt("b", 40)); |
| * |
| * // Close the writer, finalizing the sstable |
| * writer.close(); |
| * </pre> |
| * |
| * Please note that {@code CQLSSTableWriter} is <b>not</b> thread-safe (multiple threads cannot access the |
| * same instance). It is however safe to use multiple instances in parallel (even if those instance write |
| * sstables for the same table). |
