I understand that this is implemented in the command line client, but what about the C-API (and what other connectors you may distribute)?

To show progress report information, a *client* needs to support it - not just the *API*. From all the clients, only mysql command line client and mytop support this at the moment. And the page says it. C-API itself is not a "client", as far as I can see it, it's an API.

I think I misunderstood your question. I'm sorry. You mean "whether C-API supports progress reporting" - and the answer is "yes, absolutely". But originally I thought you were asking "what is the C-API or this feature, how one can add progress reporting support to his MySQL client".

Re: [Maria-developers] WL#202: Extend progress reporting
The question is whether you can compile your own client(s) with this option. In other words 'add to the list'. I am not a coder so I do not understand the full details of the document. I just do not find a clear statement in plain words (not code) that a client may be built with this option in addition to the 2 that ship with MariaDB 5.3 and what the requirements are. BTW: *Webyog* is NOT a *client*. It is a *company. Clients *are *SQLyog* and *MONyog* (and the latter is actually also a *server* at the same time! :-) Peter On Thu, Jun 30, 2011 at 15:46, Sergei Golubchik wrote: > Hi, Peter! > > On Jun 30, Peter Laursen wrote: > > I did already.

Re: [Maria-developers] WL#202: Extend progress reporting
Let me add that the reason I am asking is that for us (MONyog in particular) it would be interesting to support it. To do so will we need to replace the client library/C-API to the one shipped with MariaDB 5.3? -- Peter On Thu, Jun 30, 2011 at 16:02, Peter Laursen wrote: > The question is whether you can compile your own client(s) with this > option.

ESTIMATE.: 120 PROGRESS NOTES: DESCRIPTION: Log skeletons for queries in server (live from parser) but without constants with statistics. Things to consider: * Should use a fixed memory size. Queries should be removed as FIFO * Small CPU overhead * IN(a,b,c) should be equal recorded as IN(#) (One constant) * multi row inserts needs to be handled as one insert. We also need a method to do regular expression replacement for table names. This is needed to be able to recognize similar tables like log tables with a _YYMMDD prefix. Statistics to collect per query: - Number of times executed - Total time executed (in microseconds) - Rows read, inserted, updated and deleted.

ESTIMATE.: 200 PROGRESS NOTES: DESCRIPTION: Information_schema falls apart when there is millions of tables. Fix is to add a table dictionary of the existing files into a mysql.dict file and use this instead of the file system to return information schema queries that doesn't require a table to be opened. When we try to access a table that doesn't exists in the dictionary, we should open it to see if the .frm file exists and if yes, add it to the dictionary. In a similar fashion, if a table that should exist doesn't, we should remove it from the dictionary. We would also need a refresh command to update the dict from the .frm file (to be used if one copies a table over an old table with different information).
