#### Driver Support ####
|
|
|
|
|
HikariCP has two modes of operation: *Delegation* and *Instrumentation*. *Instrumentation* is approximately 20-40% more
|
|
|
|
|
performant, but both are exceedingly fast.
|
|
|
|
|
|
|
|
|
|
##### Delegation #####
|
|
|
|
|
Delegation mode is supported for *all* JDBC drivers.
|
|
|
|
|
|
|
|
|
|
##### Instrumentation #####
|
|
|
|
|
Instrumentation mode is supported for specific JDBC drivers. If your favorite database is not supported, drop us a note
|
|
|
|
|
in the [Google group]() and we'll try to add support for it. Below is a table of drivers that are supported and their
|
|

|
status:

<sub><sup>1</sup>Other driver versions for a given database will *probably* work, because class names are rarely changed. But
|
|
|
|
|
if it does not work, you will known quickly because HikariCP will likely fail to start. In this case, you can simply
|
|
|
|
|
force *delegation mode* (see properties below).</sub><br/>
|
|
|
|
|
<sub><sup>2</sup>The *DataSource* is specified because it is by the specified DataSource name that HikariCP looks up the instrumentation
|
|
|
|
|
information in the internal codex.</sub>
