----------------------------
Summary: Limit Memory Consumption for Read Operation
Key: GEODE-9752
URL: https://issues.apache.org/jira/browse/GEODE-9752
Project: Geode
Issue Type: Improvement
Components: redis
Affects Versions: 1.15.0
Reporter: Wayne
The "read" commands can be made more memory friendly by streaming back their
result to netty a "batch" at a time. They can get the netty ByteBuf and write
the result directly to it. Once the buffer contains a certain number of bytes
(say 4k) it do a write and flush. Once that completes it can then use the same
buffer to send the next 4k bytes to the client. Writing the response directly
to the netty ByteBuf will also produce less garbage. The only downside to it is
that the writing will be done while holding the stripe lock. This probably will
not be any slower unless the buffer fills up while we still hold the lock. The
last buffer (the one that is not full) can be done after the lock is released
just as we currently do by returning a RedisResponse outside the lock and then
asking it to write itself to netty.
