ws_ora's Issues
rewrite WsStat case class
We need a constructor with parameters LONG, CNT.
to eliminate code like this
WsStat(
currTs, 0,
new FixedList[CacheGetElm](cfg.getcntHistoryDeep),
new FixedList[CacheCleanElm](cfg.getcntHistoryDeep),
new FixedList[ConnStat](cfg.getcntHistoryDeep)
)
in def refCache
Add new field src in response of service
In response, we need the source of data: cache, db
For example:
{
"status" : "ok",
"src" : "cache",
"data" : {
...
Change output data json format
Change output json format from "by cells" into array of array
"rows" : [
[
{
"name" : "ID",
"value" : "2"
},
{
"name" : "PARENT_ID",
"value" : "null"
},
{
"name" : "NAME",
"value" : "Контрактация"
},
{
"name" : "IS_EXISTS_META_PROPS",
"value" : "0"
}
],
to
[
[
{"ID" : 5},
{"PARENT_ID" : null},
{"NAME" : "Показатели"},
{"IS_EXISTS_META_PROPS" : 1}
],
[
{"ID" : 6},
{"PARENT_ID" : 5},
{"NAME" : "Показатели 2"},
{"IS_EXISTS_META_PROPS" : 0}
]
]
Change interpretation of parameter reftables
Now in "reftables" parameter we set the list of tables on which the cache item depends, for example
"reftables" : [
"admin.t_roles",
"admin.t_users_roles",
"data.table1",
"storage.table2"
]
We need to use masks:
- depends on all tables in any schema.
"reftables" : [
"*.*"
]
- depends on some tables and all table in schema admin.
"reftables" : [
"admin.*",
"data.table1",
"storage.table2"
]
Slow simple select
Simple query (four numeric columns)
select * from XXXXX where rownum <= 8000
takes about 27 seconds.
improvement run method
In file Main.scala we need rewrite the run method and eliminate using
Runtime.global.unsafeRun
Bug with column datatypes
Service return for PKG_WIDGET.GET_DASHBOARD
"is_widget" => 1.0
"icon_add_basic_set" => 1.0
we need exactly
"is_widget" => "1"
"icon_add_basic_set" => "1"
Need use real data type for data columns
Add the mode parameter convType
We need to use the mode parameter convType str(default), num in function getColumnWsDatatype
to fetch all columns from DataSet with getString or getXXX -depends on column type.
Add wildcard to ref tables names
For example, instead of
"reftables" => ["msk_arm_lead.widget_meta_property",
"msk_arm_lead.widget_type"]
we can use
"reftables" => ["msk_arm_lead.widget_*"]
