Given that we cant use -g 1 and no change on caller side, is there any way to perform gc upon each .z.pg? I initially have .z.pg:{ bigresult: value x; .Q.gc[]; bigresult };but the memory is not going down until next smaller query.

Hi,I have a date partitioned HDB that stores a big number of trades. e.g.:trade:([] date; sym; time; side; size; price)While the machine only have enough memory to host data for 1 or 2 days, we want to find the med trade size across past 30 days.i.e....

table is a list of dictraze a table is thus just like you raze a list of dictlater dict will thus append/overwrite by key

A q session would keep running if u didn't call exit or // Assigning port or not doesn't matter

We implement the q as a data publsher,� by reusing u.q to manage the subscribing clients, The java subscribes to it via .u.sub and q publishes to all subscribers with .u.pubKei

For JDBC, you can refer to http://code.kx.com/wiki/Cookbook/InterfacingWithJavaDefault setup of KDB has no entitlement service, you need to implement the service yourself by overriding various .z handles (http://code.kx.com/wiki/Reference)
