Expression operations for Aerospike.operate/4.
Expression operations evaluate an Aerospike.Exp on the server. Reads return
the expression result under the requested response bin name; writes store the
result into the target bin.
Aerospike.operate(cluster, key, [
Aerospike.Op.Exp.read("projected", Aerospike.Exp.int_bin("count")),
Aerospike.Op.Exp.write("computed", Aerospike.Exp.int(99))
])This module accepts the expression builders exposed by Aerospike.Exp; it
does not accept arbitrary encoded payloads.
Summary
Types
Options accepted by expression operate builders.
Opaque expression operation for Aerospike.operate/4.
Functions
Reads the result of a server-side expression into bin_name.
Writes the result of a server-side expression to bin_name.
Types
@type flags() :: atom() | [atom()] | non_neg_integer() | {:raw, non_neg_integer()}
Options accepted by expression operate builders.
Supported key:
:flags- expression read or write flags. Defaults to:default.
@type opts() :: [{:flags, flags()}]
@opaque t()
Opaque expression operation for Aerospike.operate/4.
Functions
@spec read(String.t() | atom(), Aerospike.Exp.t(), opts()) :: t()
Reads the result of a server-side expression into bin_name.
The optional :flags value accepts :default, :eval_no_fail, or a list
of those atoms. Compatibility callers may pass a non-negative integer; use
{:raw, integer} when deliberately sending an unnamed server value.
Aerospike.Op.Exp.read("projected", Aerospike.Exp.int_bin("count"))@spec write(String.t() | atom(), Aerospike.Exp.t(), opts()) :: t()
Writes the result of a server-side expression to bin_name.
The optional :flags value accepts :default, :create_only,
:update_only, :allow_delete, :policy_no_fail, :eval_no_fail, or a
list of those atoms. Compatibility callers may pass a non-negative integer;
use {:raw, integer} when deliberately sending an unnamed server value.
