Below code i am giving 1000 batch size to insert query into Azure sql db its taking so much time 20 min to process 3 lakh data Is there any way to reduce the time ? also tried increasing batch size getting deadlock for 2000 batch count

LOGGER.info(“Persisting containers {}”, containers.size());

  Integer batchSize = config.getContainerDbInsertBatchSize();
  for (List<ContainerDE> subList : Iterables.partition(containers, batchSize)) {
    List<MapSqlParameterSource> parameters = new ArrayList<>(batchSize);
    for (ContainerDE containerDE : subList) {
      parameters.add(convertToMap(containerDE));
    }
    try {
      namedJdbcTemplate.batchUpdate(DatabaseQueryConstants.CREATE_CONTAINER, parameters.toArray(new SqlParameterSource[0]));
    } catch (DuplicateKeyException duplicateKeyException) {
      LOGGER.warn("Duplicate key exception occurred while persisting containers ", duplicateKeyException);
    }
    catch (Exception e) {
      LOGGER.error("Exception while persisting data for containers", e);
      throw new InfraException("Exception while persisting data for containers", e);
    }

Tried with batching
