With eventlogging data we "normally" drop data that is older than 90 days, will this work? 

Thanks for the prompt response.

If the data is going to be retained but would just become harder to query (i.e. still in Hadoop but not in mysql), maybe we could nuke data that's more than a year old (or 6 months old or something) from mysql?

We could blacklist this schema from the mysql database, and still keep producing it.  It would be available in Hadoop either way.

Hi Nuria,

FWIW: Although I'm not using this right now, but I could see it being useful for understanding the impact of new notification updates that are coming down the pike.[1][2]

What are the costs involved in keeping this schema up?

Best,

Roan:

The data for Echo schema(https://meta.wikimedia.org/wiki/Schema:Echo) is quite large and we are not sure is even used. 

Can you confirm either way? If it is no longer used we will stop collecting it.


Thanks, 

Nuria
