restrictQueries amount step maxTimeInMs

Collects some DB queries. Tries to reach at maximum 'amount' queries. Uses at maximum 'maxTimeInMs' milliseconds in 'step' millisecond stints.

setImmutable :: Resource -> Boolean -> <ReadGraph> ()
withServiceMode :: Boolean -> Boolean -> (() -> <b> a) -> <b> a
withServiceMode allowImmutableWrites createAsImmutable fn

runs function fn so that:

  • when allowImmutableWrites is True, fn is allowed to write to immutable clusters
  • when createAsImmutable is True, any new database clusters created by fn will be immutable
