Feature Description
In bulkload data import scenarios, typically, the data volume of each bulkload transaction is relatively large, ranging from several hundred MB to GB. Therefore, the data within a bulkload transaction is saved in temporary data files before being committed, which reduces and controls memory overhead. For unordered data (such as secondary index data) in a bulkload transaction, external merge sorting is performed during the transaction commit phase.
tdstore_bulk_load_total_merge_buffer_size is used to specify the total size, in bytes, of the memory buffer for external merge sorting during a BulkLoad transaction.
