Summary: Dynamic Resource Reservations
Key: MESOS-2018
URL: https://issues.apache.org/jira/browse/MESOS-2018
Project: Mesos
Issue Type: Improvement
Components: allocation, framework, master, slave
Reporter: Adam B
Assignee: Michael Park
This is a feature to provide better support for running stateful services on
Mesos such as HDFS (Distributed Filesystem), Cassandra (Distributed Database),
or MySQL (Local Database).
Current resource reservations (henceforth called "static" reservations) are
statically determined by the slave operator at slave start time, and individual
frameworks have no authority to reserve resources themselves.
Dynamic reservations allow a framework to dynamically/lazily reserve offered
resources at task launch time, such that when that task completes, those
resources will only be re-offered to the same framework (or other frameworks
with the same role).
This is especially useful if the framework's task stored some state on the
slave, and needs a guaranteed set of resources reserved so that it can
re-launch a task on the same slave to recover that state.
