* Match origin log messages
- Demote per-file printouts to "debug" level.
* Print an all-files stat summary for whole replay (begin/summary)
- At info level, like origin
Prompted by dtest that expects origin log output.
v2:
* Fixed broken + operator
* Use map_reduce instead of easily readable code
Schema is tracked in memtable and cache per-entry. Entries are
upgraded lazily on access. Incoming mutations are upgraded to table's
current schema on given shard.
Mutating nodes need to keep schema_ptr alive in case schema version is
requested by target node.
Discern fatal and non-fatal excceptions, and handle data corruption
by adding to stats, resporting it, but continue processing.
Note that "invalid_arguement", i.e. attempting to replay origin/old
segments are still considered fatal, as it is probably better to
signal this strongly to user/admin
Align with rest of file (for better or worse). This allows calls from
entity without query_processor handy (i.e. storage_proxy).
Added "minimal" setup method for the "global" state, to facilitate
tests. Doing a full setup either in cql_test_env or after it is created
breaks badly. (Not sure why). So quick workaround.
Updated the current two users (batchlog_manager and commitlog_replayer)
callsites to conform.
* Removes previous, accidental fix that got committed.
* Instead just do not give RP:s to replay mutations. This is same as in Origin,
and just as/more correct, since we intend to flush the data to sstables
asap anyway
After killing scylla in the middle of a write, the next scylla
instance failed to finish commit log replay, showing the following
error message:
scylla: core/future.hh:448: void promise<T>::set_value(A&& ...)
[with A = {}; T = {}]: Assertion `_state' failed.
After a long debug session, I figured out that check_valid_rp() was
triggering the exception replay_position_reordered_exception, which
means replay position reordering.
Looking at 8b9a63a3c6, I noticed that database::apply is guarded
against reodering, but commitlog replay code is not.
