1. Parquet Avro schema mismatch errors when ingesting are sometimes silently ignored due to race-condition in BoundedInMemoryExecutor. This was reproducible when running long-running delta-streamer with wrong schema and it caused data-loss
2. Fix behavior of Delta-Streamer to error out by default if there are any error records
3. Fix a bug in tracking write errors in WriteStats. Earlier the write errors were tracking sampled errors as opposed to total errors.
4. Delta Streamer does not commit the changes done as part of inline compaction as auto-commit is force disabled. Fix this behavior to always auto-commit inline compaction as it would not otherwise commit.
The code-style rules follow google style with some changes:
1. Increase line length from 100 to 120
2. Disable JavaDoc related checkstyles as this needs more manual work.
Both source and test code are checked for code-style
