<p>⢠RPC end point: Drill exposes a low overhead protobuf-based
RPC protocol to communicate with the clients. Additionally, a C++ and Java API
layers are also available for the client applications to interact with Drill.
Clients can communicate to a specific Drillbit directly or go through a
ZooKeeper quorum to discover the available Drillbits before submitting queries.
It is recommended that the clients always go through ZooKeeper to shield
clients from the intricacies of cluster management, such as the addition or
removal of nodes.</p>

parse incoming queries. The output of the parser component is a language
agnostic, computer-friendly logical plan that represents the query.</p>

<li><p><strong>Runtime compilation</strong>:
Runtime compilation is faster compared to the interpreted execution. Drill
generates highly efficient custom code for every single query for every single
operator. Here is a quick overview of the Drill compilation/code generation
process at a glance.

<li><p><strong>Optimistic and pipelined query execution</strong>: Drill adopts
an optimistic execution model to process queries. Drill assumes that failures
are infrequent within the short span of a query and therefore does not spend
time creating boundaries or checkpoints to minimize recovery time. Failures at
node level are handled gracefully. In the instance of a single query failure,
the query is rerun. Drill execution uses a pipeline model where all tasks are
scheduled at once. The query execution happens in-memory as much as possible to
move data through task pipelines, persisting to disk only if there is memory
overflow.
