Feature: Cache to disk long running transactions to allow faster recovery

[bersler]

Is your feature request related to a problem? Please describe.
When the source database contains a long running transaction (like for 24h+) the recovery after restart takes very long and requires to start parsing of redo logs from very old redo log file.

Describe the solution you'd like
Cache to disk long running transactions so during recovery (after forced reboot for example) the program can restore information about long running transaction from disk and would not need to start reading from very old redo log file.

Describe alternatives you've considered
None

Additional context
This feature might add requirement for disk space.
