go to post Dmitry Maslennikov · Jul 10 SSL Error for this driver does not really mean it's SSL ERROR, in most cases it could mean, that connection can't be established, from the first step. Check if port really available, you could try it by using some different tools, like DBeaver. And unfortunately I can't recommend this driver you trying to use, it's unstable. May throw sigfault errors randomly and have other bugs. I would recommend using this driver instead, in most scenarios both are compatible, this one just more stable and predictible. And this driver used by lots of other Python projects, like SQLAlchemy, Django, irissqlcli, and more based on them.

go to post Dmitry Maslennikov · Jun 10 Ages ago I've impleted project named BlocksExplorer, with a various of ways of using it One of them is generating a picture of of the database, and visualization of defragmentation. I think I tried it once on 2TB Database, but that was long time ago. Anyway, this tool generates picture in BMP format, where each pixel represents each block in the database, so, for For 2TB database, it will be around 268435456 blocks, that will be a picture 16384x16384, and in BMP with a 3 bytes per pixel, it will be around 768MB for this picture, quite big one This project is fully open, you can try to modify it a bit, and maybe if you do it per global, you will be able to make a map

go to post Dmitry Maslennikov · Apr 16 Did you try using more appropriate package %Stream for it? In your case, you would need to use %Stream.FileCharacter Set stream=##class(%Stream.FileCharacter).%New() $$$ThrowOnError(stream.LinkToFile("c:\export.csv")) set rs = ##class(%SQL.Statement).%ExecDirect(, "SELECT a, b FROM table") if rs.%SQLCODE'=0 { throw ##class(%Exception.SQL).CreateFromSQLCODE(rs.%SQLCODE, rs.%Message) } while rs.%Next() { set line = $listbuild(rs.a, rs.b) do f.WriteLine($listtostring(line, ",")) } $$$ThrowOnError(stream.%Save()) Additionally, nowadays using embedded classes does not give much advantage, if it's not for one row result, only makes the code a bit harder to read

To help with it we need to significantly increase codebase in GitHub in ObjectScript, so that AI will have something to learn from.

go to post Dmitry Maslennikov · Mar 16 The value should be static, at the time of creating record on table For dates it uses range feature, so, you can split it by months, year (I suppose) and move the whole bunch of records including indexes to another databse
go to post Dmitry Maslennikov · Mar 16 While we moved our application to AWS, and we have some data, which we need to keep for a while. With this feature, we can move old data to a cheaper storage. I believe the ability to move to a cheaper storage is mostly the case. Another option is that some table is too big, and someone would like to split it to be stored in multiple different databases, together with the indexes.
