Vladislav Pyatkov updated IGNITE-17732:
---------------------------------------
Description:
The transaction protocol requires locks on different entities (keys, rowIds,
tables and indexes), but our implementation ready is appliable for only one
type.
By the reason, a transaction will lock only keys (PK of those rows which
participate in the transaction). All another locks will be temporarily
mitigated.
As a temporary workaround for this disadvantage, supposed:
# Create a NL (Not a lock) lock mode, which is compatible for all another mode
# All lock modes on rowIds, tables, indexes should convert to NL
was:
The transaction protocol requires locks over different entities (keys, rowIds,
tables and indexies) all indexes (now it is a pk) in the same manner as it
happens for data (locks on {_}RowIds{_}). But lock manager cannot resolve all
problems in his case (in particular, waiter for _RowId_ does not create when
the lock on index have not got).
As a temporary workaround for this disadvantage, supposed:
# Create a NAL (Not a lock) lock mode, which is compatible for all another mode
# All lock modes on PK should convert to NAL
> Only keys should be locked in transaction
