Excellent. Let me know if my version of the message works for you.

Re: Introduce the ability for a user to manage binary types [IGNITE-13154]
Hi, I change the error message [1]. The suggestion at the message contains info about requirement to remove all data with old schema, then remove metadata by control.sh or manually by delete files and restart grid.

Re: Introduce the ability for a user to manage binary types [IGNITE-13154]
Glad to see it coming! That was a pain in the neck. Could we also add a hint to the exception message when a type mismatch happens? Basically, the exception should not only report details about the mismatch but also suggest how to solve it. The text can mention these new control.sh commands and advise to remove the old metadata. - Denis On Thu, Jun 18, 2020 at 7:42 AM Taras Ledkov wrote: > Hi, > > I propose to introduce ability for a user to manage cluster binary types. > This functionality is useful when user needs to change schema without > cluster restart. > > Motivation: > Rid users of manual operations in the folder 'binary_meta' and cluster > restart when they need change schema. > > The proposed implementation contains restrictions (see [1]). > So I guess we add internal API and command for public command line tool > (control.sh) > with mode 'experimental' mode (the property > IGNITE_ENABLE_EXPERIMENTAL_COMMAND must be set). > > Please take a look at the ticket / patch. > > Any comments / suggestions? > > [1]. https://issues.apache.org/jira/browse/IGNITE-13154 > > -- > Taras Ledkov > Mail-To: tled...@gridgain.com > >
Introduce the ability for a user to manage binary types [IGNITE-13154]
Hi, I propose to introduce ability for a user to manage cluster binary types. This functionality is useful when user needs to change schema without cluster restart. Motivation: Rid users of manual operations in the folder 'binary_meta' and cluster restart when they need change schema. The proposed implementation contains restrictions (see [1]). So I guess we add internal API and command for public command line tool (control.sh) with mode 'experimental' mode (the property IGNITE_ENABLE_EXPERIMENTAL_COMMAND must be set). Please take a look at the ticket / patch. Any comments / suggestions? [1]. https://issues.apache.org/jira/browse/IGNITE-13154 -- Taras Ledkov Mail-To: tled...@gridgain.com
