Python client: create cache with expiration policy

[kulinskyvs <ku...@gmail.com>]

Hello all,

I'm wondering whether it's possible to create a cache with  expiration
policy <https://apacheignite.readme.io/docs/expiry-policies>   defined from
Python client?

Documentation says nothing about this.

Thank you in advance.

Hi,

Looks like Python API should be improved.

I created the ticket on this:

https://issues.apache.org/jira/browse/IGNITE-11965

BR,
Andrei

Yes, it's my fault. I double check the list of existed options and looks like
there is no expire policy option there.

I see that exists PROP_EAGER_TTL property:

https://apacheignite.readme.io/docs/expiry-policies#section-eager-ttl

But there are no options for expiration policies. 

Let me some time to check the source code.

BR,
Andrei

Hi,

Are we talking about the same? I mean, my goal is to create a cache (if not
yet created) with some predefined expiration policy in order to be able to
set the expiration timeout for key/value pair put into Ignite.

Looks like  you are referring to
https://apacheignite.readme.io/docs/partition-loss-policies,
while I'm interested in https://apacheignite.readme.io/docs/expiry-policies.

Thanks.

Best regards,
Vadzim Kulinski

Hi,

Yes, it should be possible. Please read the documentation from binaries:

https://github.com/apache/ignite/blob/master/modules/platforms/python/docs/datatypes/cache_props.rst

PROP_PARTITION_LOSS_POLICY:

Partition loss policy: READ_ONLY_SAFE=0, READ_ONLY_ALL=1, READ_WRITE_SAFE=2,
READ_WRITE_ALL=3, IGNORE=4

BR,
Andrei
