> We need to provide more user-friendly information about locked objects in
> LOCKS system view.
> At the moment, the value returned by the {{toString()}} method of the
> {{LockedKey}} class is displayed as the value of the locked object
> (OBJECT_ID).
> Example:
> ||OWNING_NODE_ID 1||TX_ID|| OBJECT_ID || MODE ||
> | ilsvt_n_0 | 0193537b-2340-0001-3668-6b4e00000001 | LockKey [ctx=17,
> key=java.nio.HeapByteBuffer[pos=0 lim=3 cap=3]]
> | X |

> A more readable output format needs to be defined and implemented.
> For example:
> {noformat}
> INDEX_ID=<ID>, partition=<ID>, key=<VALUE>,
> TABLE_ID=<ID> partition=<ID> rowId=<ROWID>
> {noformat}
> The format and information we can display must be agreed upon with the
> engineers working on the transaction protocol.
