Well, I guess you'd need to browse
hello
how can we get the final executed plan i.e at run time in monetdb.
as pysical-algebra-plan only shows the result after compilation time.
And at runtime what does it acually does i.e after sampling what does it decide
i.e type of join or others thing also.

Is the cost model used at compile time or at runtime for estimation of
cardinalities

We are working on linux so any way through jdbc

You can enable the ODBC debug output by your ODBC configuration.
For example:
Trace = Yes
TraceFile = /tmp/debug.log
ForceTrace = Yes

We want to debug the monetdb server , in other words we want final execution
plan and query execution times etc.
We are working on linux so any way through jdbc
Just as a sidenote: JDBC vs OBDC is not necessarily a question of the OS;
both JDBC and ODBC are available and supported on
can be represented as node in tree
We are not able to use that , actually that is giving error

Where can i find the description of BAT_select?

hello Is there a cluster(column consists of many clusters) based joining. If
so than is there different algo used for each cluster also.
What is the difference between (b=tmp_2607) and b=tmpr_2610 Is there any big
differece between them. And any time real BAT ids of (id given at time of
hello
Where I can find the full flow diagram of execution of monetdb.
Apart from that We are printing the BATcacheid of the columns passed to the
BATfetchjoin function ,We are getting the different BATCacheids .
So what is the reason behind that.
hello
I was talking about flow diagram image, so that i can visualize that.

hello
Are BATcacheid's real column id's i.e those BATid's which are given at
the time of storage of the document(static id's).
If no than from where we can print those static BATid's

Does anybody have any idea ...
