So I will be very puzzled, in the case of not adding a shared lock to the row, will there be no conflict between the transaction id of the transaction 1 accessing the row and the transaction id of the transaction 2 modifying the row?
Assume that a data conflict happens when two transactions access the same record in the database within an interval of 5 units. At least one write operation is performed on the record. For example, Input: (T1, A, 0, R) (T2, A, 2, W) ...
Some of the worker threads did print out to stderr- but these statements were never referenced in the thread checker's conflict messages, and they never caused a problem in practice. I'd behappy to have an explanation in any case. Translate 0 Kudos Copy link Reply David_M_Intel...

It has some performance improvement if read-write conflict happens frequently. But in Skywalking, reading operation happens every 3 seconds. Read-write conflict happens rarely in this time period. So I'm not sure if it's necessary to change code. First about this, I understand. From my under...
Static solutions of conflict handling by utilizing shadow copies have been suggested, even under non-preemptive object access (where shadow copies are almost useless). This paper reports on research concerning adaptive preemptive methods for handling record-based read/write access to objects providing ...
