NAME
Myriad::Storage::Implementation::Perl - microservice storage abstraction
SYNOPSIS
DESCRIPTION
This is intended for use in tests and standalone local services. There is no persistence, and no shared data across multiple processes, but the full Myriad::Storage API should be exposed correctly.
get
Takes the following parameters:
$k- the relative key in storage
Returns a Future which will resolve to the corresponding value, or undef if none.
set
Takes the following parameters:
$k- the relative key in storage$v- the scalar value to set
Note that references are currently not supported - attempts to write an arrayref, hashref or object will fail.
Returns a Future which will resolve on completion.
getset
Takes the following parameters:
$k- the relative key in storage$v- the scalar value to set
Note that references are currently not supported - attempts to write an arrayref, hashref or object will fail.
Returns a Future which will resolve on completion.
observe
Observe a specific key.
Returns a Ryu::Source which will emit the current and all subsequent values.
push
Takes the following parameters:
$k- the relative key in storage$v- the scalar value to set
Returns a Future which will resolve to .
unshift
Takes the following parameters:
Returns a Future which will resolve to .
pop
Takes the following parameters:
Returns a Future which will resolve to .
shift
Takes the following parameters:
Returns a Future which will resolve to .
hash_set
Takes the following parameters:
Returns a Future which will resolve to .
hash_get
Takes the following parameters:
Returns a Future which will resolve to the scalar value for this key.
hash_add
Takes the following parameters:
Returns a Future indicating success or failure.
hash_keys
Takes the following parameters:
Returns a Future which will resolve to a list of the keys in no defined order.
hash_values
Takes the following parameters:
Returns a Future which will resolve to a list of the values in no defined order.
hash_exists
Takes the following parameters:
Returns a Future which will resolve to true if the key exists in this hash.
hash_count
Takes the following parameters:
Returns a Future which will resolve to the count of the keys in this hash.
hash_as_list
Takes the following parameters:
Returns a Future which will resolve to a list of key/value pairs, suitable for assigning to a hash.
