Hi,

Hope you are all well !

I cannot insert this query, and I have an error

@x0rzkov Hello. Can you please provide the script/code snippet which we can use to reproduce this issue?

ghost · 2020-02-21T11:28:40Z

Hi,

Hope you are all well and thanks for the reply !

I just made you a repository in order to test my use case.
Ref. https://github.com/x0rzkov/manticore-test

How to run:

Pre-requisites

docker
docker-compose

Before

tar xvf manticore-dump.sql.tar.gz

Run

docker-compose up --build

Importer (options)

% importer -h
  -h, --help                    display help
  -f, --input-file string       input-file (default "/opt/manticore/data/manticore-dump.sql")
  -m, --manticore-host string   input-file (default "localhost")
  -p, --manticore-port uint16   input-file (default 9312)
  -j, --parallel-jobs int       parallel-jobs (default 2)

Quick important note:
I do not understand how to add the rt_attr_multi tags in the limostar index.
How do you build the query for real time indexes ?

Cheers,
X

Since it's different from the mentioned in this issue's body I want to ask - is the the error which concerns you now?

I do not understand how to add the rt_attr_multi tags in the limostar index.

It's already there:

snikolaev@dev:~/manticore-test$ cat manticore.conf |grep -A 20 "index limostar"
index limostar {
    type = rt
    rt_mem_limit = 1024M
    path = /var/lib/manticore/data/limostar

    rt_attr_bigint = remote_id
    rt_field = avatar
    rt_attr_string = owner
    rt_attr_string = name
    rt_attr_string = url
    rt_attr_string = language
    rt_attr_bigint = watchers
    rt_attr_bigint = stars
    rt_attr_bigint = forks
    rt_attr_bigint = size
    rt_attr_string = license
    rt_attr_timestamp = pushed
    rt_attr_timestamp = created
    rt_attr_timestamp = starred
    rt_attr_string = service_id
    rt_attr_multi = tags

How do you build the query for real time indexes ?

What query do you mean?

ghost · 2020-02-24T07:25:26Z

Now I have another error,

So the idea is to check if manticore's go-sdk can absorb lots of data. That's simply it, and this repo is a good occasion to test your sdk.

For How do you build the query for real time indexes ?
What is the sphinxql query to add multiattr to limostar index ? Give me just an example how to add all the tags per star.

Thanks in advance for your insights per advance.

Ps. It is quite urgent as we have to decide if we have to continue to use manticore or not.

manticoresearch · 2020-02-25T07:53:00Z

Try workers=thread_pool. In this case I get the error as I showed above - "index out of range [1] with length 1" and it seems it's a bug in the SDK.

What is the sphinxql query to add multiattr to limostar index ?

mysql> alter table limostar add column tags2 multi;
Query OK, 0 rows affected (0.07 sec)

mysql> alter table limostar add column tags3 multi64;
Query OK, 0 rows affected (0.04 sec)

mysql> alter table limostar add column tags4 string;
Query OK, 0 rows affected (0.05 sec)

Give me just an example how to add all the tags per star.

mysql> insert into limostar(tags2,tags3,tags4) values((1,2,3),(1,2,3),'a b c');
Query OK, 1 row affected (0.00 sec)

mysql> select tags4 from limostar where tags4 any ('c', 'd');
+-------+
| tags4 |
+-------+
| a b c |
+-------+
1 row in set (0.00 sec)

ghost · 2020-02-25T07:58:13Z

Hi,

Thanks a lot for the reply, I am working with @x0rzkov and will try out now the query for tags.

When do you think that the sdk can be fixed ?

Best Regards,
Luc Michalski

manticoresearch · 2020-02-25T10:23:39Z

@lucmichalski

When do you think that the sdk can be fixed ?

I'm afraid not today. Perhaps not even this week. What I can recommend is you could just use a mysql Go library to connect to the mysql's Manticore port (9306 in your docker compose). The binary protocol which the SDK implements might give very insignificant performance benefit, what it gives is mostly just an abstraction layer for more convenient development, but it seems that in your app (at least what you have shared) it may be not that important.

Also if you're looking for max INSERT/REPLACE throughput and you have lots of incoming docs make sure you do batching as it increases the throughput significantly. Here is what we recently measured on one of our customers's single server with standard linux mysql client + GNU parallel:

With batch=10K+32 parallel workers I could get the insert throughput of a single RT index =
14892 docs per second 
13.71MB (of source data + sql overhead) per second
= 1.12TB per day

There’re 32 cores on the server. They were ~1/3 loaded:

It works fine with the mysql driver, even with 15 parallel jobs !

Please, update us when you have fixed the sdk.

Thanks in advance

Hello.
I've looked into you code and see following pattern: you've created one client, and then try to use it in parallel from bunch of goroutines. That way it will not work anyway: once client connected, you can use it serial way, sending query-by-query and reading response after each of them. There is only one socket opened, and daemon expects one flow of commands; you can't share one and same among parallel works.

So, you just need to create an instance of client for every separate coro. Then each one will have own connection which is not shared with anothers, and the crashes must go out.

I tried with only one thread, and the bug is also triggered, at list with the go-sdk.

I've just tried minute ago:

cl := NewClient()

res, err := cl.Sphinxql(`REPLACE into limostar (id,remote_id,avatar,owner,name,fullname,description,homepage,url,language,watchers,stars,forks,size,pushed,created,starred,service_id,license) VALUES ('96285','22486533','https://avatars2.githubusercontent.com/u/2347603?v=4','00-Evan','shattered-pixel-dungeon','00-Evan/shattered-pixel-dungeon','Traditional roguelike game with pixel-art graphics and simple interface','unkown','https://github.com/00-Evan/shattered-pixel-dungeon.git','Java','623','623','279','29628','2020-01-13 02:41:56 +0100 CET','2014-07-31 23:56:31 +0200 CEST','2020-02-18 11:32:08 +0100 CET','github','unkown')`)
	fmt.Println(res, err)

and get [Query OK, 1 rows affected] <nil>.

Full test clause looking like this:

func TestClient_Sphinxql_insert(t *testing.T) {

	cl := NewClient()

	_, err := cl.netQuery(commandPersist, buildBoolRequest(true), nil)

	res, err := cl.Sphinxql(`REPLACE into limostar (id,remote_id,avatar,owner,name,fullname,description,homepage,url,language,watchers,stars,forks,size,pushed,created,starred,service_id,license) VALUES ('96285','22486533','https://avatars2.githubusercontent.com/u/2347603?v=4','00-Evan','shattered-pixel-dungeon','00-Evan/shattered-pixel-dungeon','Traditional roguelike game with pixel-art graphics and simple interface','unkown','https://github.com/00-Evan/shattered-pixel-dungeon.git','Java','623','623','279','29628','2020-01-13 02:41:56 +0100 CET','2014-07-31 23:56:31 +0200 CEST','2020-02-18 11:32:08 +0100 CET','github','unkown')`)
	fmt.Println(res, err)
	res, err = cl.Sphinxql(`replace into testrt values(2,'another subject', 'more content', 15)`)
	fmt.Println(res, err)
	res, err = cl.Sphinxql(`replace into testrt values(5,'again subject', 'one more content', 10)`)
	if err != nil {
		fmt.Println(err.Error())
	} else {
		fmt.Println(res)
	}
}

it works as expected.
What is daemon version you run on? May be something wrong there?
