So there seems to be 3 statistics rows for this table.   And low and behold there is the 
"numrows = 49" which I see the indexStat when I turn on tracing.


First thought is I didn't think we needed any statistics at all
for a single column primary key.
There should be entries in this catalog for every index on a table, so it is not necessarily expected to be one per table. I think for each index there is an entry for each column in the index (actually the stat applies to multiple columns so in a 3 column index I think there is an entry for (col1), (col1,col2), and (col1, col2, col3). But looking at your ddl I would only expect 1 entry, as there is one 
index on the table, and it has one column.  I am not sure what the
expectation is for the foreign key that matches the primary key, maybe
it is 2 rows?

I do wonder if the foreign key is causing some extra issues.  I think
in the long past we would end up creating 2 indexes in this case and
they would be exactly the same.  So functionality was added to just
"logically" create the index and it would rely on the underlying
physical index sort of "shared" by the primary key on id and the foreign
constraint on id.  We have had bugs in this area in the past and wonder
if it left an "orphan" row in the statistics.

Interesting that the second column it looks like it was created in 2010.
seems like there might be multiple problems here. It would be great to figure out how the multiple rows got in there in the first place. I would suggest seeing what the system does for ddl in a brand new database, turn off index stat thread, run your ddl, add some rows to the table, and hand run update statistics procedure. 

I would not be surprised if existing code does not expect the number of
rows you are seeing. If this is really a buggy orphan row, probably best zero admin fix is to change the update statistics code to look for 
other rows and delete them.
you can follow the update statistic code starting at:
java/engine/org/apache/derby/impl/sql/execute/AlterTableConstantAction/updateStatistics

There may be a index stat daemon bug here too, but I think it might just
be getting confused by the bad data in the catalog.  Maybe it just keeps
reading all the rows and queueing work, but calling update statistics only update 2 of the 3 rows. 



I ran:

VALUES syscs_util.syscs_check_table('PKG_9145E_V1', 'BC01_CONFIGURATION_SET')

And this returns that the table is okay.

I ran:

VALUES syscs_util.syscs_check_table('SYS', 'SYSSTATISTICS')

And this returns that the table is okay but I am not sure this is even valid.

So the question is how/why are there 3 sets of statistics for this table.  Here 
is the DDL for the table:

    CREATE TABLE "PKG_9145E_V1"."BC01_CONFIGURATION_SET"
    (
       ID int PRIMARY KEY NOT NULL
    );
    ALTER TABLE "PKG_9145E_V1"."BC01_CONFIGURATION_SET"
    ADD CONSTRAINT BC01_CONFIGURATION_SET_FK_1 FOREIGN KEY (ID) REFERENCES 
"CORE_V1"."CONFIGURATION_SET"(ID) ;

Here is one such table.   This is killing performance.

Here is the statistics for this table:

There are in fact 38390 rows in the table.

Here is some of the stats trace:

Any idea where I can look in the code?  I would patch Derby if necessary

I don't have the code in front of me, but could you maybe trace the creation of 
the statistics objects, with the goal of finding out where the lower number is 
coming from?
I think if you start looking in maybe CursorNode, possibly TableDescriptor, you 
should be able to get somewhere.

Maybe you'll find that the lower number corresponds with an earlier/older 
version of the statistics for the index?
(a theory being that a stale statistics object is being read)


Just some late night ramblings,

The application is hitting the table PKG_9145E_V1"."BC01_CONFIGURATION_SET 
frequently.   Many rows are being added and deleted but the total number of rows is not 
really changing that much if at all.

Is the table completely emptied at any point?

[bb] No, the table is never empty at any point during this.    Basically about 
300 rows being deleted and 300 new rows being added about every 30 seconds.

Do you run anything else than insert and delete (with predicate) that modifies 
the table?
No, in fact the table has only one column:

CREATE TABLE "PKG_9145E_V1"."BC01_CONFIGURATION_SET"
(
   ID int PRIMARY KEY NOT NULL
)
;
ALTER TABLE "PKG_9145E_V1"."BC01_CONFIGURATION_SET"
ADD CONSTRAINT BC01_CONFIGURATION_SET_FK_1 FOREIGN KEY (ID) REFERENCES 
"CORE_V1"."CONFIGURATION_SET"(ID) ;


What I don't understand is the line:

abs(log(49) - log(44727)) = 6.816...

t-est is the estimated number of rows as seen by the table [conglomerate], 
whereas i-est is the estimated number of rows as seen by the current index 
statistics. These are very different, and based on the output below, it appears 
t-est is correct when it says the number of rows is 44'727 [1]. So why isn't 
i-est changing?

[bb] exactly my question.


What do you see if you look at the results from querying SYS.SYSSTATISTICS?
(i.e. columns STATISTICS [2] and CREATIONTIMESTAMP) What's the relevant DDL for 
the indexes/constraints in question?

So it seems that even just recently this morning, it still thinks that the 
index only has 49 rows

The same values are being shown each time.  Is this correct?

At least i-est seems off.
Do/did you see similar problems with other tables/indexes?
You can check the values by doing a select count and looking at the statistics 
stored in the system table.

Today there are 44621 rows.   I was running some test over night and did do 
some deletes that would cause this to go down.

I am trying to tune the indexStat daemon so that it will run when needed but 
not too frequently.    With the default value, I was seeing about a 20% penalty 
when running the application and saw the indexStat daemon nearly non-stop.   So 
I adjusted the lndiffThreshold to be 4.0 an it is not running too frequently 
but I still would like to understand what the trace/log is telling me.

A lndiffThreshold of 4.0 means the table has to grow (or shrink) by a factor of 
roughly 54.6. In the specific case above, the index statistics for the table 
shouldn't be generated again before there are ([3]) nearly two and a half 
million rows in it (or less than 820).
I'd say a threshold of 4.0 is pretty relaxed - do you expect the 
distribution/cardinality of the values to be similar for a table with 50K rows 
and 2500K rows?

[bb] I have other tables that are constantly being inserted into where each 
record will be unique.  The table has 2 indexes on it where one is unique and 2 
will have duplicates.   This table will end up with about 42M records in a 
week, will stay around for 2 weeks and then will be empty again and not used 
for 50 weeks of the year.   Basically there is one table per week of the year 
that starts as empty, is populated for the week, data stays around for 2 weeks 
for query purposes, and then is purged out.   The important thing is that once 
the week table starts to be populated, queries will start hitting that table so 
it is important that the queries use the indexes on the table.   The table is 
inserted at a rate of about 60 records/second so after a few thousand records I 
want the statistics to be generated and the indexes to be used.

So maybe 4.0 is too much but 1.0 was generating statistics constantly.

I copied a line from below:
[q/p/s=0/268/268,err:k/u/c=0/0/0,rej:f/d/o=0/303/0]
q = queued
p = processed
s = scheduled
k = known errors (the daemon is prepared for these and can easily recover) u = 
unknown errors c = consecutive errors (daemon will disable itself if there are 
too many consecutive errors) f = rejection due to full queue d = rejection due 
to duplicate request (already in the queue) o = other (currently only tracks 
scheduling attempts when the daemon has been disabled)


FYI, I'm aware that your options to fine-tune the statistics generation is 
rather limited.

[1] "wrote stats for index X (id): rows=44727, card=[44727]"
[2] In ij I had to cast this to see everything: cast(STATISTICS as VARCHAR(40)) 
[3] Or rather before Derby believes there are so many rows in the table -  
we're working with estimates here.


Here is a snippet of the output:
