Eric, I'm looking for a way to eliminate the construction, transmission, and parsing of the long multi-row INSERT queries that we are issuing from our client app. Since we are inserting 200k rows a shot, we're looking for every boost that we can find. * Connecting: (3) [want to use a connect

Shawn, Very Interesting idea. I definitely want to look into this a bit more. I fear though that the bin-logs might be written first to disk before they are copied over to the replicas. Another member of my team mentioned there might be a way to issue direct MyISAM table INSERTS. She suggested

Hi! I'm looking for a better way to insert large numbers of rows from a client application that is sampling physical data in real-time. In our case, we are using a C "double hipvalues[100]" cyclical array to buffer our sampled values. We're currently creating large query strings similar to

Does anyone know when INDEX DESC will be implemented? I'm storing time values and want to access the data from the most recent time value without sorting the result set. Thanks! -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com

Data spikes and buffering inserts...

Hi! My MyISAM database works perfectly for 98% of the cases that we encounter. However, there are a few cases during our experiment that we know will cause spikes in dataflow. We know both the why and when, so we are trying to plan appropriately for it. Is there a way that I can mix in memory i
