Subject Re: Replacing default work dir from tmp to current dir
Date Thu, 03 Oct 2019 11:03:12 GMT
Nikolay,

Ignite is widely used in embedded scenarios; the ability to process data
in-process locally is very powerful and I see no reason why we should
remove it. I absolutely agree with Pavel T. on the subject. As an example,
both SQLite, and rocksdb are distributed as a library, so I see no issues
in Ignite server side being a library.

As long as Ignite is available as a maven library, we should provide a
consistent node behavior; "current directory" as persistence directory is
not consistent.
