Big Slowdown (15-20X ) on import functions in Monetdb October 2014 Release
by Ashish Kumar Singh 28 Nov '14

28 Nov '14

All, With October,2014 release we are stucked in to very strange performance issue while importing data on virtualised environments. On Virtual machines in our local VMware servers and amazon machine we are seeing import performance has downgraded to close to 15 to 20 while importing ~ 2000 files as compared to 1 hour time being taken with old release. This we are seeing consistently with CentOS, SLES vm and configuration is 4 Core 33 GB machine. We tried on quite a few amazon vm just to make sure its not an issue with a particular instance setup. On a physical machine of 4 core 24 GB we are able to match speed of import with old monetdb. We are issuing copy into command through JDBC connection. Can you guys help me with pointers on this issue, I will be happy to share any debug info. Regards, Ashish Kumar Singh Mobile: +91-9972045095 Skype: toashishk(a)gmail.com

handling of (indirect) division by zero: nulls or an error?
by g4＠novadsp.com 27 Nov '14

27 Nov '14

I posted earlier about a problem with 'type mismatch' being reported. The root cause is quite simple: it is returned if the stddev_pop() function is used in a select that returns zero rows. Given that the count of the population (N) is used as the denominator in the calculation this makes sense. A question arising then is this. If one has assembled a more complex list of aggregate functions in a query, would it be better for null to be returned instead of an error? i.e. select count(weight), sum(weight), average(weight) where (no rows are selected) => 0,null,null Should this not also be the case if stddev_pop is included? select count(weight), sum(weight), average(weight), stddev_pop(weight) where (no rows are selected) => 0,null,null,null Instead of 'type mismatch' ? TIA. J.

Announcement: New Oct2014-SP1 Bugfix release of MonetDB suite
by Sjoerd Mullender 27 Nov '14

27 Nov '14

The MonetDB team at CWI/MonetDB BV is pleased to announce the Oct2014-SP1 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Oct 2014-SP1 bugfix release MonetDB5 Server * Fixed adding of 0 intervals to dates. Build Environment * The libraries included in the Windows installers have been upgraded. We now use libxml2-2.9.2, openssl-1.0.1j, pcre-8.36, and zlib-1.2.8. MonetDB Common * Implemented a change to the way in which string bats are appended. We now try harder to limit the growth of the string heap. * Fixed some problems with BATsample. It was possible for BATsample to return a value that was just beyond the end of the sampled BAT. Also, on some systems the range of the rand() function is rather limited (0..32767) and trying to get a sample larger than this range would result in an infinite loop. SQL * Fixed sys.queue() implementation to report on other queries being executed. * A number of bugs were fixed in the code to upgrade a database from previous releases. This version should fix the upgrade of a database that had been upgraded to the Oct2014 release, but also properly upgrade directly from Jan2014 and Feb2013 releases. Bug Fixes * 3580: cosmetic change (append newline) * 3609: Incorrect use of generate_series * 3611: quantile() and median() commands crash when used 2x on the same variable on a null table * 3612: assertion failure when deleting rows from table to which a FK constraint is defined * 3620: ORDER BY broken when using UNION ALL * 3621: Hexadecimal literal vs decimal literal

'type mismatch' error

Using both mclient and C#/C++ test clients connected via 64bit ODBC I am encountering this type mismatch error for no obvious reason. This is something of a show-stopper for what had proved to be a very interesting experiment! # MonetDB 5 server v11.19.3 "Oct2014" # Serving database 'dbfarm', using 4 threads # Compiled for x86_64-pc-winnt/64bit with 64bit OIDs dynamically linked # Found 15.982 GiB available main-memory.

Loading RDF data
by Rinke Hoekstra 26 Nov '14

26 Nov '14

Hi All, After some fiddling, I managed to compile and install the latest version of MonetDB with RDF support enabled (turns out it requires an old version of Raptor... 1.4). My next step would be to load some actual RDF data... but I cannot find any mention of how to do this on the MonetDB website, nor in the mailinglist archives. Pointers very welcome. Thanks, Rinke ---- Rinke Hoekstra VU University Amsterdam/University of Amsterdam

support for window aggregates and window frames ...
by Jay Prasad 24 Nov '14

24 Nov '14

Does MonetDB support window aggregates and window frames? >From the documentation it looks like it supports only window rank functions. Queries of the form: SELECT saleyear, salequarter, sum(saleamount), sum(saleamount) OVER ( PARTITION BY saleyear ORDER BY salequarter ASC) AS partitionedsaleamount FROM ds_1108_null_advent_1580276965 group by saleyear, salequarter; fail with this error: SELECT: function 'sum' not found However, the code seems to include branches that process window aggregates. See sql_parser.y (line 3530) and rel_select.c (line 4658). I am also seeing a similar issue with window frames: SELECT saleyear, salequarter, EXTRACT (MONTH FROM orderdate) AS monthofsale, SUM(saleamount) AS totalsales, RANK() OVER ( PARTITION BY monthofsale ORDER BY SUM(saleamount) ASC ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) AS rank FROM ds_1108_null_advent_1580276965 GROUP BY saleyear,salequarter,monthofsale ORDER BY saleyear ASC LIMIT 20; TypeException:user.s16_1[60]:'algebra.subsort' undefined in: (_103:any, r1_103:any, r2_103:any) := algebra.subsort(_92:int, r1_100:bat[:oid,:oid], r2_100:bat[:o id,:oid], _83:bit, _99:bit) program contains errors NOTICE: This e-mail message and any included attachments are from Infogix, Inc.

JDBC driver: Statement#setMaxRows()
by Robert Koch 24 Nov '14

24 Nov '14

I have big tables with billions of rows. If I click accidentally on DBVisualizer's data tab, or, if the data tab of a small table is opened and I click on a big table, DBVisualizer tries to retrieve all rows. Then I have to kill DBVisualizer process and/or the DB server process. Answer of DBVisualizer's team: "Hi Robert, It seems like the JDBC driver does not implement the Statement#setMaxRows() method. Please contact your driver developer about this problem." Is the Statement#setMaxRows() method implemented?

Whicht GUIs/Frontends are you using? / MonetDB support in DBVisualizer
by Robert Koch 24 Nov '14

24 Nov '14

Which tools are you using? As mentioned, I am using DBVisualizer for work with MonetDB. I asked for a better support of MonetDB in DBVisualizer: "MonetDB is the leading open-source, column-oriented, analytical in-memory database. MonetDB's community is growing and MonetDB does not come along with a frontend. It would be great to have a native support out of DBVis." This is the answer: "Hi Robert, We have an open ticket for addressing support for MonetDB in DbVisualizer. Currently the number of requests for it is low so I cannot say when or if it will happen. Most of the database specific support is expressed in a so called database profile in DbVisualizer. This is a single XML file which defines up to 80% of the functionality for a database. The database profile framework is documented in the users guide and if you are looking for improved MonetDB support I suggest you look into building a database profile for it. http://confluence.dbvis.com/display/UG91/Database+Profiles If you have any related questions please don't hesitate to contact us." I somebody out there, who is interested in MonetDB support in DBVisualizer, willing to build a database profile XML file?

JDBC driver: sorting columns? - DatabaseMetaData#getColumns()
by Robert Koch 24 Nov '14

24 Nov '14

I am using DBVisualizer via JDBC to work with MonetDB. When exporting tables with DBVisualizers @export function, columns are sorted alphabetically, which causes problems when LOADING the exported csv into another database, and the import tool is expecting the original order of columns. I wrote to the DBVisualizer team, they answered as follows: "Hi Robert, Export uses the column order reported by the JDBC driver, so please consult your driver developer to see if you can get the driver fixed. More specifically, DbVisualizer uses the column order as reported by the DatabaseMetaData#getColumns() method." If MonetDB JDBC driver is actually sorting columns, could you please return the given order of table columns?

Multithreaded prob
by Doug Service 18 Nov '14

18 Nov '14

I have installed MonetDB and and started using it through MAPI. The documentation indicates that opening multiple connections from separate threads in a single process is supported. I perused the MAPI source and it appears that all of the Monet data structures used are associated with the connection. In our application the threads will be independent and processing similar but unique data sets each with its own connection to the database. No threads will share a database connection nor attempt to use another threads connection. Does anyone have experience using multiple threads in a single process each accessing a separate database MonetDB MAPI connection they would like to share? Did you have any problems? Doug Service

Operations on Network Addresses
by Tim Burress 14 Nov '14

14 Nov '14

Hello, I'm a relatively new user and have run into a problem which may just be a misunderstanding. I'm using the Oct2014 version, installed on Fedora 20 from the MonetDB rpm repository. When I try to query a database using inet "containment" operators like << or <<= it seems that the operators are not recognized: sql> select src,dst from raw.ids where src << inet'xxx.xxx.xxx.xxx/27'; SELECT: no such binary operator 'left_shift(inet,inet)' sql> select src,dst from raw.ids where src <<= inet'xxx.xxx.xxx.xxx/27'; syntax error, unexpected '=' in: "select src,dst from raw.ids where src <<=" Other ordinary binary inet operators seem OK: sql> select src,dst from raw.ids where src = inet'xxx.xxx.xxx.xxx'; (prints out table) sql> select src,dst from raw.ids where src < dst; (prints out table) However the documented functions do not seem to be recognized: sql> select masklen(inet'192.168.0.0/24') SELECT: no such unary operator 'masklen(inet)' sql> select netmask(inet'192.168.0.0/24') SELECT: no such unary operator 'netmask(inet)' So it seems that support for network address types is only partially available in this release. Is that normal? Do I need to rebuild from source in order to get them? Thanks! Tim

Here is the log file: 2014-11-11 08:54 INFO Creating new connection for [{Default group}/DRMAX - DEV] for driver=nl.cwi.monetdb.jdbc.MonetDriver and URL=[jdbc:monetdb://lux-dev1-ana.dev.ceosdata.com:50000/zkdev1] 2014-11-11 08:54 INFO Adding ClassLoader URL=file:/home/rbiciste/tools/lib/monetdb-jdbc-2.12.jar 2014-11-11 08:54 ERROR Error connecting to the database using URL=jdbc:monetdb://lux-dev1-ana.dev.ceosdata.com:50000/zkdev1, username=drmaxtst SELECT: no such operator 'tracelog' [SQL State=08001] java.sql.SQLException: SELECT: no such operator 'tracelog' at nl.cwi.monetdb.jdbc.MonetConnection.<init>(MonetConnection.java:254) at nl.cwi.monetdb.jdbc.MonetDriver.connect(MonetDriver.java:171) at workbench.db.DbDriver.connect(DbDriver.java:429) at workbench.db.ConnectionMgr.connect(ConnectionMgr.java:228) at workbench.db.ConnectionMgr.getConnection(ConnectionMgr.java:158) at workbench.gui.components.ConnectionSelector.doConnect(ConnectionSelector.java:233) at workbench.gui.components.ConnectionSelector$2.run(ConnectionSelector.java:133) Caused by: nl.cwi.monetdb.mcl.MCLException: SELECT: no such operator 'tracelog' at nl.cwi.monetdb.mcl.net.MapiSocket.connect(MapiSocket.java:311) at nl.cwi.monetdb.mcl.net.MapiSocket.connect(MapiSocket.java:398) at nl.cwi.monetdb.mcl.net.MapiSocket.connect(MapiSocket.java:252) at nl.cwi.monetdb.jdbc.MonetConnection.<init>(MonetConnection.java:232) ... 6 more Any help would be appreciated.

Announcement: New Oct2014 Feature release of MonetDB suite
by Sjoerd Mullender 11 Nov '14

The MonetDB team at CWI/MonetDB BV is pleased to announce the Oct2014 feature release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Important consideration when upgrading to this release. In this release we have fixed bug 3474. This bug made it possible that there were duplicates despite there being a unique or primary key constraint present. This could only happen for multi-column constraints. MonetDB maintains an internal column containing a hash for multi-column constraints, and there was a bug in the maintenance code of this column. During an upgrade, this column needs to be recreated. This is done by dropping and adding back the constraints. If there are no duplicates, adding back the constrains should work without problem, but if there are duplicates, adding the constraints will fail. There is unfortunately no easy way to tell the user, so after having made the first connection to the server (when the upgrade happens), check the merovingian log (if you use merovingian -- also known as monetdbd) or the server output window (if you don't use merovingian). Jaql support is removed. The experimental code for Jaql support has been removed. If you have RPM or DEB packages for Jaql installed from an earlier version (MonetDB-jaql and monetdb5_jaql respectively), you will need to uninstall them before the upgrade. Known issue when upgrading old versions. We have noticed that upgrading directly from a version older than the Jan2014 release gave an error. Upgrading to Jan2014 first and then on to Oct2014 should work. Backup. As always, make a backup of your databases before upgrading. Oct 2014 feature release MonetDB5 Server * Removed algebra.materialize. * Removed algebra.kunique and algebra.tunique. They were subsumed by algebra.subunique. * Remove algebra.antiuselect and algebra.thetauselect. They were subsumed by algebra.subselect. * Removed algebra.topN and its imlementation BATtopN. The function was not used. * Removed aggr.histogram and its implementation BAThistogram. The function was not used, and did not produce output in the "headless" (i.e. dense-headed) format. Histograms can be created as a by-product of group.subgroup. Build Environment * Jacqueline, the MonetDB/JAQL frontend, has been removed. The frontend never grew beyond being experimental, and there is no interest anymore to maintain the code. Merovingian * monetdb create: add -p flag to set monetdb user password on creation, and therefore allow creating the database in unlocked state mapilib * Changed mapi_timeout argument from seconds to milliseconds. stream * Changed mnstr_settimeout function so that the specified timeout is now in milliseconds (used to be seconds), and that it also needs an extra argument specifying a callback function (no arguments, int result) that should return TRUE if the timeout should cause the function to abort or continue what it was doing. MonetDB Common * Added "multifarm" capability. It is now possible to separate persistent and transient BATs into different directories (presumably on different disks). This can be done by using the --dbextra option of mserver5 (see the man page). SQL * Added PostgreSQL compatible string TRIM, LTRIM, RTRIM, LPAD and RPAD functions * Stop support for upgrading directly from a database created with a server from the Oct2012 release or older. You can upgrade via the Feb2013 or Jan2014 release. Bug Fixes * 2945: evaluation of SQL "between SYMMETRIC" requires MAL iterator because there is no (bulk) MIN/MAX(a,b) * 3204: monetdb create: allow setting admin password during creation * 3390: Missing definition for pushSht in monetdb5/mal/mal_builder.h * 3402: We should have a C implementation of mal.multiplex. * 3422: Segmentation fault after large table insert * 3459: incomplete implementation of JDBC driver getNumericFunctions(), getStringFunctions(), getSystemFunctions(), getTimeDateFunctions(), getSQLKeywords() methods in MonetDatabaseM * 3471: JDBC driver: incorrect output result of SQL query: SELECT 1 ; * 3474: bulk and scalar versions of mkey.rotate_xor_hash differ * 3484: COPY INTO on a file works fine on Linux/OSX, but not on Windows * 3488: Slow SQL execution for correlated scalar subquery * 3489: SQL query with ORDER BY does not order its result as requested * 3490: SQL query kills the mserver5 (Segmentation fault) * 3491: SQL query kills the mserver5 (Segmentation fault) * 3493: Test monetdb5/modules/mal/Tests/pqueue.mal fails since recent checkins * 3494: Tests monetdb5/modules/mal/Tests/pqueue[23].mal lack correct/expected/intended output * 3495: Test sql/test/centipede/Tests/olap.sql lacks correct/expected/intended output * 3497: monetdb start reports crash in merovingian.log * 3498: SQL throws TypeException if aggregations and limit statements are both present * 3502: Database was killed by signal SIGBUS * 3504: COPY INTO does not allow OFFSET without specifying amount of records * 3505: expression with <boolean> = NOT <boolean> returns a syntax error but NOT <boolean> = <boolean> not * 3506: conversion to varchar terminates mserver * 3508: conversion of string '0 ' to type smallint or integer fails * 3510: timestamp + month interval generates bogus MAL? * 3511: When having multiple selections combined with aliases not all of them seem to be evalauted. * 3512: auto-conversion of string to `sht` type no longer works * 3513: COPY BINARY INTO fails on 6gb file; works fine on 3gb * 3516: inserting '0' into a column of datatype numeric fails * 3518: UNION with subqueries * 3521: large results of function exp() are not automatically returned as double * 3522: SQL catalog table sys.columns lists columns for table ids which do not exist in sys.tables * 3523: Window function over union gives no result * 3524: wrong error on missing aggregation column * 3527: select distinct - order by - limit 2 results in one single result * 3528: segfault at mal_session.c:521 * 3532: several geom tests crash after manifold changes * 3534: missing table name with invalid column in join using (and problems after resolving it) * 3536: program contains error with join using integer and smallint * 3542: gdk/gdk_bat.c:2904: BATassertHeadProps: Assertion `!b->H->revsorted || cmp >= 0' failed. * 3543: invalid behavior and incorrect data results for SQL data type: numeric(4,4) * 3544: sys.reuse() corrupts data * 3546: Division by zero in CASE statement that should avoid it * 3547: Empty query when selecting a field from a view made of UNION ALL * 3551: Wrong ticks in TRACE * 3552: incorrect data results for "WHERE int_col <> 0" * 3554: Issue with subselect and ORDER BY * 3555: Order of evaluation inside CASE WHEN * 3558: numeric values (as strings) are incorrectly parsed/converted and invalid strings are accepted without error * 3560: Error "BATproject: does not match always" with subselect/groupby/having * 3562: mserver5: gdk_bat.c:2855: BATassertHeadProps: Assertion `!b->H->revsorted || cmp >= 0' failed. * 3563: incorrect results for scalar function locate(in_str, search_str, occurrence) * 3565: Wrong/confusing error message when trying to add a FK to a TEMP TABLE * 3572: Table names with escaped double quotes are rejected * 3573: alter table alter_not_null_test alter test set NOT NULL; is accepted when test contains null.
