Add pessimistic_write_or_fail and pessimistic_partial_write support for mysql Closes: typeorm#6530

Nice, thanks for adding this! Any idea how fast this can be pushed into the next release? |
|
Probably have to add a check for the driver version so it doesn't get used on earlier MySQL versions. |
|
Thank you for contribution! As @nebkat mentioned, we need to add a version check (can be added into test itself) in order to prevent CI fail. |
|
@pleerock added the tests with version checks. CI passes now. |
|
Probably outside the scope of this PR but seeing as all the checks in |

Thank you for contribution! 🎉 |

Adds
SKIP LOCKED(pessimistic_partial_write) andNOWAIT(pessimistic_write_or_fail) support for Mysql drivers.Database support as follows
Added test cases, but they do not pass with the current versions listed in docker-compose. (Have tested with the versions listed above and they pass). Generally, how does typeorm handle cases like this?
