Merge lp:~vlad-lesin/percona-server/i_s-innodb-changed-pages into lp:~laurynas-biveinis/percona-server/xtradb-changed-page-tracking

[Vlad Lesin]

Trying once more. The initial branch is lp:~laurynas-biveinis/percona-server/xtradb-changed-page-tracking .

Remade the test. Now it creates redo log records twice as much as the redo log size. As the 1st half is guaranteed to be tracked it checks if the number of tracked pages is greater than or equal to the number of first half. Also it checks if innodb-file-per-table is set and a new table is created and inserted to, then part of the records must have space id equal to the new table space id and "low" page ids;

[Laurynas Biveinis (laurynas-biveinis)]

Some feature design and code questions. Maybe not all of them need to
be resolved right now.

- We need to know somehow if the current run is complete, i.e. if we
  query some LSN interval, the last block we read should have the last
  block bit set, if we silently output partial data, the user will not
  know if he should re-query the last part of LSN interval or not. I
  am not sure what would be the best way. Another column for last
  block bit flag? That would be quite clumsy for users to use.

- Likewise I am not sure what should we do about corrupted blocks in
  the middle of requested LSN intervals (and maybe missing LSN
  interval data too). Another boolean column "this block is continuous
  from the previous block"?

- In any case I guess we should diagnose bad block checksums we
  encounter to the error log at least. That's easy, but it raises the
  issue of what would happen if the I_S query would attempt to read the
  last bitmap block while it's being written. Currently such block
  would be ignored correctly, but in this case we would get false
  errors. I think we should introduce a log online mutex for the last
  written block protection. Acquire it in the log writer around the
  block write + sync. Acquire it (and immediatelly release) in the
  log iterator right before the read when (offset == file size - 1
  block).

General comments:

- Please submit an MP against lp:percona-server/5.1, as the current
  target branch has been merged.

- I guess the current code did not implement the index condition
  pushdown yet?

- There is no decision on the I_S table row count limit system
  variable in the blueprint, but the code has it, please update the
  blueprint.

- Please add tests for LSNs too. Unfortunately, their values are not
  that predictable, so the basic test would be to check that start lsn
  < end lsn.

- Please add tests for the index condition pushdown, i.e. where
  start_lsn > ... and end_lsn < .... The lsn values for this test can
  be taken from the 1st query on I_S, and get the e.g. MIN, MAX, and
  median values of the tracked interval.

- The new system var requires a new sys_var/var_name-basic.test. In
  the current branch, isn't sys_vars/all_vars test failing due to that
  test being missing?

- Code formatting issues (I know, these are very pedantic): the
  /*=====*/ under function names should match the function name
  length. The function arg comments should start with /*!< in: or /*!<
  out: or /*!< in/out:

- Indentation issue around diff lines 308--312: both args and code
  should be indented by 1 tab. Likewise in many other places in
  log0online.c etc.. Also there should be 1 tab between var type and
  name in the local var declarations.

- (srv_changed_pages_limit ? output_rows_num < srv_changed_pages_limit
  : TRUE) can be simplified to (!srv_changed_pages_limit ||
  output_rows_num < srv_changed_pages_limit)

- Maybe log_online_bitmap_iterator_init should set the rest of the
  fields it does not touch now to some safe values?

- No need for the comment in diff lines 618--620, 646--648, it should
  be enough to mention it once in log0online.c next to the first file
  name printing place.

-...

Maybe it's better to wait until log tracking thread completely write all blocks for certain lsn interval?

About holes. We could to have another I_S for holes and bad blocks recognition. Another option you described below:

It's easy to recognize bad blocks just ckecksum checking. And we could read lsn interval completely before output which allows us to recognize not completely written lsn intervals checking "last block" flag at the end of interval. We could use linked list of changed pages inside of iterator instead of just one page to hold lsn range.

Yes, mutex would help us to avoid reading not completely written blocks. But what about partially written lsn intervals? Maybe that mutex should protect the whole interval writing? Not only one block?

The purpose is to hide implementation of iterator. We can change the content of iterator and some work logic not changing the code which uses the iterator.

Such wait could be very long on a busy server that starves the log following thread.

Can you describe in more detail how you imagine this another I_S table?

But the issue is not the detection of bad or missing data, but rather what to do when this situation happens.

It probably depends on what we decide to do for the above questions.

Ah, I see, thanks. I assumed this was not the case, because the struct itself was in a header file.

Ok, let's back to the purpose of the table at all. As I understood, the purpose is to have some statisticts to see how it's going on, maybe to anylize something. This table is not for precise calculations, as I understood, it is for estimations. At the other hand It would be usefull to see if there is something wrong with bitmap files in information schema. So I propose to leave the table as is. The name of the table is "Changed pages". It shows changed tables. It doesn't guarantee real time information mapping by design. I don't think it is really important to show the last written blocks or lsn intervals if they are not completely written at the moment of table generation. As for holes or bad blocks we could just ignore them due to purpose of this table.

But I propose to have two addiditional tables. One for bad blocks (previous page id, previous lsn range, bitmap file name, start bad block offset, number of bad blocks). And one for holes (start lsn, end lsn, bitmap file name, number of written blocks).

Done.

It does.
 if (cond && !cond->val_int())
  continue;

cond->val_int() traverses the condition tree and calculates condition value using fields values stored earlier.

But we discussed it would be useful to recognize
"START_LSN >some_value_1 and END_LSN < some_value_2"
expression to prevent scanning the rest of bitmap file(s)
after reaching the upper limit.

In progress.

The condition can be any, not only start_lsn >... and end_lsn <... .
And the size of the table is limited with that condition. As I understood
the main purpose of condition pushdown for this table is to limit memory size
for storing temporary table. How can we test that size? Beside that the condition
is checked twice. The first is during table generation and the second is during
query execution. So it may be situation when we get right query execution result
but pushdown doesn't work and the table were completely stored in memory before
output. So how it can be tested?

I'm afraid I don't understand your idea. Do you offer to make several queries with the
following "where" expressions?
1) start_lsn > 0 and end_lsn < ($max_lsn/2)
2) start_lsn > 0 and end_lsn < $max_lsn
3) ($max_lsn/2) >= 0 and end_lsn < ($max_lsn)

If yes, what expected results should be?

I think my mistake is in wrong naming of the variable type. It isn't a system
variable, it's plugin variable. Jenkins build didn't show any problems with variable tests.
And I saw another innodb_* variables without tests in sys_var test suite.

Looks OK, but 1) I wonder if we have to distinguish between a hole and a bad block, 2) is it that important for the user to have this info queriable through I_S because the main table is "best effort" only. Please check with Vadim.

Yes, it is impossible to test completely. Maybe let's add a WHERE start_lsn > .. AND end_lsn < ... query to tests but don't call it an ICP test. But perhaps it's not useful at all.

I had 1) in mind.

Well, about anything. That limits the usefulness, I agree.

The main trouble is we need common mysql code to implement this. For example to traverse
condition tree we need to know the type of Items, but they are defined in sql/item*.h.

So we could place the function which traverses condition tree to recognize our pattern
in common mysql code somewhere near calc_lookup_values_from_cond() and use it as
external function in handler/i_s.cc but I doubt it's a good solution.

At the other hand we could make it common enough to be placed in common code like
calc_lookup_values_from_cond().

I mean we could parse the following patterns:
 - some_expression & cmp
 - cmp & some_expression
 - cmp & cmp
 - cmp
where cmp is:
 - some_field (<|<=) uint_value
 - uint_value (>|>=) some_field
 - some_field (<|<=) uint_value
 - uint_value (>|>=) some_field
to the following structure:
{
  string field_name1;
  uint field_value1;
  string field_name2;
  string field_value2;
}

And the purpose of the function would be to get maximum field
value after which there is not sense to scan table/file/something else.
As the code is common enough to be used not only for our I_S table generation
it could be placed to the common mysql code.

Any opinions/ideas?

I think the distinguish is in units of measuring.
Bad block is a page range while hole is lsn range.

I believe it's OK to include sql/*.h in the innodb handler/ source files. But then it needs checking if InnoDB built as a plugin can link to all the symbols it needs.

If the above works, then I think let's keep it local to i_s.cc at first for now.

Looks good. I'd tweak the top-most recognized pattern to be
term & term & ... & term
Where
term can be a "cmp", as defined above, or anything else (ignored)
Then maintain a lower and upper bound for the range and go through each cmp looking if it enables to reduce the range.

+  This function parses condition and gets upper bounds for start and end LSN's
+  if condition corresponds to certain pattern.
+
+  We can't know right position to avoid scanning bitmap files from the beginning
+  to the lower bound. But we can stop scanning bitmap files if we reach upper bound.
+
+  It's expected the most used queries will be like the following:
+
+  SELECT * FROM INNODB_CHANGED_PAGES WHERE START_LSN > num1 AND start_lsn < num2;
+
+  That's why the pattern is:
+
+  pattern:  comp | and_comp;
+  comp:     lsn <  int_num | lsn <= int_num | int_num > lsn  | int_num >= lsn;
+  lsn:	    start_lsn | end_lsn;
+  and_comp: some_expression AND some_expression  | some_expression AND and_comp;
+  some_expression: comp	| any_other_expression;
+
+  Suppose the condition is start_lsn < 100, this means we have to read all
+  blocks with start_lsn < 100. Which is equivalent to reading all the blocks
+  with end_lsn <= 99, or just end_lsn < 100. That's why it's enough to find
+  maximum lsn value, doesn't matter if this is start or end lsn and compare
+  it with "start_lsn" field.
+
+  Example:
+
+  SELECT * FROM INNODB_CHANGED_PAGES
+    WHERE
+    start_lsn > 10  AND
+    end_lsn <= 1111 AND
+    555 > end_lsn   AND
+    page_id = 100;
+
+  max_lsn will be set to 555.

 Sometimes there is a need to take a binary log and apply it to a database with 
 a different name than the original name of the database on binlog producer.
 
-If one is using statement-based replication, he can achieve this by grepping
-out "USE dbname" statements out of the output of mysqlbinlog(*).  With
-row-based replication this is no longer possible, as database name is encoded
-within the the BINLOG '....' statement.
-
-This task is about adding an option to mysqlbinlog that would allow to change 
-the names of used databases in both RBR and SBR events.
-
-Varible :variable:`rewrite-db` of **mysqlbinlog** utility allows to setup rewriting rule "from->"to".
+New variable rewrite-db has been added to the mysqlbinlog utility that allows the changing names of the used databases in both Row-Based and Statement-Based replication. This was possible before by using tools like grep, awk and sed but only for SBR, because with RBR database name is encoded within the BINLOG ‘....’ statement.
+
+Variable :variable:`rewrite-db` of **mysqlbinlog** utility allows to setup rewriting rule "from->"to".
+
+Example
+=======
+
+**mysqlbinlog** output before rewrite-db ::

  Fast Index Creation
 =====================
 
-Percona has implemented several changes related to |MySQL| 's fast index creation feature. This feature extends the ``ALTER TABLE`` command by adding a new clause that provides online index renaming capability, that is renaming indexes without rebuilding the whole table.
+Percona has implemented several changes related to |MySQL|'s fast index creation feature. Extended features, besides disabling :variable:`fast_index_creation`, can be enabled with :variable:`expand_fast_index_creation`.
 
 Disabling Fast Index Creation
 =============================
@@ -14,27 +14,6 @@
 This feature implements a session variable that disables fast index creation. This causes indexes to be created in the way they were created before fast index creation was implemented. While this is slower, it avoids the problem of data dictionary inconsistency between |MySQL| and |InnoDB|.
 
 
-:command:`mysqldump`
---------------------
-
-A new option, ``--innodb-optimize-keys``, was implemented in :command:`mysqldump`. It changes the way |InnoDB| tables are dumped, so that secondary and foreign keys are created after loading the data, thus taking advantage of fast index creation. More specifically:
-
-  * ``KEY``, ``UNIQUE KEY``, and ``CONSTRAINT`` clauses are omitted from ``CREATE TABLE`` statements corresponding to |InnoDB| tables.
-
-  * An additional ``ALTER TABLE`` is issued after dumping the data, in order to create the previously omitted keys.
-
-Delaying foreign key creation does not introduce any additional risks, as :command:`mysqldump` always prepends its output with ``SET FOREIGN_KEY_CHECKS=0`` anyway.
-
-
-``ALTER TABLE``
----------------
-
-When ``ALTER TABLE`` requires a table copy, secondary keys are now dropped and recreated later, after copying the data. The following restrictions apply:
-
-  * Only non-unique keys can be involved in this optimization.
-
-  * If the table contains foreign keys, or a foreign key is being added as a part of the current ``ALTER TABLE`` statement, the optimization is disabled for all keys.
-
 ``OPTIMIZE TABLE``
