Condition or Error
The number of fragments in a single transaction has been exceeded.
The maximum number of fragments within a single transaction within the network protocol is limited to 32768. If there is a very large transaction that exceeds this number of fragments, the replicator can stop and be unable to continue. The total transaction size is a combination of the fragment size (default is 1,000,000 bytes, or 1MB), and this maximum number (approximately 32GB).
It is not possible to change the number of fragments in a
single transaction, but the size of each fragment can be
increased to handle much larger single transactions. To change
the fragment size, configure the
parameter. For example, by doubling the size, a transaction of
64GB could be handled:
If you change the fragment size in this way, the service on the extractor must be reset so that the transaction can be reprocessed and the binary log is parsed again. You can reset the service by using the trepctl reset command.
