Picking the right architecture = Picking the right battles + Managing trade-offs
- Clarify and agree on the scope of the system
- User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?
sysctl -w fs.file-max=12000500
sysctl -w fs.nr_open=20000500
# Set the maximum number of open file descriptors
ulimit -n 20000000
# Set the memory size for TCP with minimum, default and maximum thresholds
sysctl -w net.ipv4.tcp_mem='10000000 10000000 10000000'
- Optional/nullable data types.
- Variant data types.
- Flag with extra information needed only in some cases (or different in different cases).
- Modeling states in a state machine where each state can have some data associated with it.
- List of operations for batch processing, where each operation can have its own arguments.
- Alternative to function overloading that allows avoiding combinatorial explosion when there are multiple parameters that need variants.
- Nested data structures with heterogenous nodes.
