# This is the desired size of the VALUES part of each INSERT or REPLACE statement executed in a single transaction.
# This is not a hard limit. The actual SQL executed might be longer or shorter, depending on the actual content imported.
# The default value is `96KiB`, which is optimized for import speed when TiDB Lightning is the only client of the cluster.
# The default value is "96KiB", which is optimized for import speed when TiDB Lightning is the only client of the cluster.

# Because of implementation details of TiDB Lightning, the value is capped at 96 KiB. Larger values are ignored.
# You can decrease this value to reduce the stress on the cluster due to large transactions.
# logical-import-batch-size = '96KiB'
# logical-import-batch-size = "96KiB"

# In Logical Import Mode, this parameter controls the maximum number of rows inserted per transaction.
# This parameter is introduced in v8.0.0. The default value is `65536` rows.
