Hi all,

Can someone elaborate on the missing features of TRANSACTIONAL_SNAPSHOT
cache mode or point me to some source of information that elaborates them?

Are there any known bugs related to it in current Ignite version?

Besides the possibility of it completely getting redone in the future, what
would other major throwbacks be if it were used in production?

Thank you very much,
Dana

Hi Dana,

Here you can find a list of known high-level limitations:
https://apacheignite.readme.io/docs/multiversion-concurrency-control#limitations

Also, the performance might not be satisfactory and not all the cluster
failure scenarios might be covered.

Generally, as of know, I would advise you to use the key-value transactions
of Ignite that are battle-tested and used in productions since the
inception of Ignite.
