Hello everyone, We are evaluating Monet right now to store and analyze a huge quantity of data. We have several facts collection that range from 1 million row, 200 cols. to way over 300 million rows and over 10.000 columns. We are aware of memory limitations of current Monet version and looking forward to the new one but in the meantime we'd like to do some performance and load tests. In order to know which data we will be able to store, we need to know how much memory will use a BAT depending on the datatype and the number of elements we want to store in it. Is there a lineal relation between those variables (ie. 8 bytes oid, 8 bytes int => 16 bytes per element) or do Monet encode data using intervals or such? Thank you in advance and kudos for your big efforts, Guillermo Arbeiza, Open Sistemas de Información e Internet garbeiza(AT)opensistemas.com ---------------------------------------------------------------------- Mensaje enviado por el servidor de openSistemas (www.opensistemas.com)

[MonetDB-users] shrinking BATs and distributed/streaming MonetDB

by Shahbaz

I was finally able to install monetdb and put data into it (on OSX), although I don't have any performance numbers to report back just yet. -If i delete or even drop a large table from MDB5, many of the BAT files remain on the file system. Is there a command that deflates/shrinks or completely removes to files? I wasn't able to find anything in the docs -According to previous messages on the mailing list and some other docs, MonetDB 5 is supposed to work with distributed databases (Armada?). I don't see anything regarding this in the docs either, is it coming soon? -I am very (VERY) interested in the ability to have a cluster/grid of MDB servers which let me distribute data and computation while providing an easy to use interface for end users and admins. Along with that, if we get the ability to process streaming data (such as stock quotes), MonetDB will become king of Wall Street :) -I see that one of the recommended projects for students is to extend MonetDB to process time series data. If someone is looking at this, please take a look at this paper: http://citeseer.ist.psu.edu/610025.html (AQuery for ordered data). Thanks

[MonetDB-users] Bug fix release of MonetDB suite

by Sjoerd Mullender

The MonetDB team at CWI, The Netherlands, is happy to announce the availability of a new bug-fix release for the major "Venus" release. New versions of all components of the MonetDB suite are released. MonetDB/XQuery The handling of updates was incomplete. Several memory mapping and concurrency problems have been fixed. Moreover, empty pages that resulted from deletion of nodes are now properly handed back to the system for reuse. MonetDB/XRPC Security and concurrency handling has been improved. MonetDB/SQL Foreign key constraint checking fixed; View in view dependencies bug fixed; Resolved crashes caused by large views; Prepared statements with more than 30 arguments now work. MonetDB/API Haskell and TCL libraries were broken and have been removed; Perl and Python libraries were broken and have been fixed. The current version of the protocol is not compatible with the previous version. Bugs fixed: [ 1579510 ] XQ: update error for "(1,2)/." [ 1590523 ] XQ: substring-after [ 1636828 ] fork() behaves strangely [ 1637867 ] XQ: seqcast int? to numeric unsupported [ 1639108 ] mserver crashes on delete query [ 1640248 ] PF: ~500 tests randomly fail on Solaris x86 [ 1644245 ] M5 & SQL5: various tests hang/timeout on Darwin [ 1648303 ] database dump does not save/restore auto-increment sequences [ 1650469 ] SQL: Armada sinks MonetDB ships [ 1651567 ] yet another delete bug, foreign key related [ 1651599 ] caching of inserts causes extreme memory consumption [ 1655818 ] SQL:Error inserting float in numeric column using JDBC [ 1655857 ] XQ: call to builtin function crashes XRPC client [ 1659889 ] SQL: sequence not restored properly [ 1644610 ] Conflict between normal query and XRPC query (and many more that hadn't been reported) -- Sjoerd Mullender

[MonetDB-users] xrpc clients

by oliver oli

hello, i'm trying to understand the design of monetdb/xquery, how it works and what are my options to use it with python / ruby. xrpc is a soap interface, is it possible to use monetdb/xquery with any soap client? in other words: could it be an alternative to the mapi interface
