what happened do the datastore statistics ?

[Alain de Raynal]

Hi everyone,

the datatore statisctics page my gae console does not let me select a specific entity kind anymore

and all the queries on the __Stat_Kind__ table return zero result.

this started 2 or 3 days ago...

is it just for my app ?

Thx,

Alain

It's working fine for me, you might want to put in a production issue.

thanks, I've just done that:

This can happen if you have large numbers of namespaces, kinds or
property names.

There is a limit to the size of the datastore_stats written for an
application (approx 10MB for apps with entities only in the empty
string namespace or 20MB for apps with entities in a non empty string
namespace). The size can be easily exceeded if there are a large
number of different datastore stats that need to be written. For
example, if a property name or a kind name is computed, then there can
be a very large number of stats entities. This then can cause the
limit to be exceeded.

If you're interested in a larger limit for datastore stats, please
file a bug so we can track how many people care about this enough.

I'd suggest in the meantime, perhaps revisiting the schema you might
be using to see if there is a way of avoiding the datastore_stat
explosion.

that must be it...

I have about 30 different entity kinds and no namespace.

how can I fix this in the short term ?

if I delete all entities of a specific type, will gae stop computing statistics for that kind ?

is there a way to specify some entity kinds that should be ignored while computing statistics ?
