Evented I/O ?

by drush66

Hi I was wondering, is there event based I/O for Pharo? Something like nio in java or EventMachine for Ruby?

Re: [Pharo-users] Serializing to/from Json

by Jan van de Sandt

Well, you can also store binary contents in CouchDB [1]. You can attach zero or more binary attachments to a Json document in CouchDB. You could use this in combination with Fuel. Add the properties you want to search for to the Json document and leave all the other data in binary format. Jan.

Not necessarily, CouchDB and MongoDB are based on the json, but some are more close to pure key value stores, where value is usually just some blob and db does not care much about. In combination with such databases Fuel is a great fit. I _think_ TokyTyran is such db, and memcached. Davorin
