This represents some of the context in which a transaction is running It summarizes all necessary requirements for Group Replication to work.
These requirements might be extracted in two different moments in time, and, as such, with different contexts:
- Startup verifications, that are extracted when Group Replication starts, and typically from global vars.
- Runtime verifications, that are extracted when a transaction is running. It it typically from session THD vars or from mutable global vars.
Please refer to the place where information is extracted for more details about it.
