If you compile too many unique scripts within a small amount of time,
Elasticsearch will reject the new dynamic scripts with a
`circuit_breaking_exception` error. By default, up to 15 inline scripts per
minute will be compiled. You can change this setting dynamically by setting
`script.max_compilations_rate`.
`circuit_breaking_exception` error. By default, up to 75 scripts per
5 minutes will be compiled for most contexts and 375 scripts per 5 minutes
for ingest contexts. You can change these settings dynamically by setting
`script.context.$CONTEXT.max_compilations_rate` eg.
`script.context.field.max_compilations_rate=100/10m`.
