Description
The JSON output of wal pretty printer is malformed and cannot be parsed.
There are 2 major issue:
- The writer classes and cell codec classes are added (as normal text) whenever a new WAL file printing starts (NOTE: WALPrettyPrinter can take multiple WAL files as input)
- The edit heap size and position are outside json formatting
These are side effects of some patches done in past which missed to cover json output scenarios.
Current sample output, which is malformed JSON:
