Rejected execution (queue capacity 50) in bulk process

Elastic Stack Elasticsearch
1

Hello,

I'm facing a problem bulk indexing 5k documents in 24 different indices
(i18n). I'm using elasticsearch 1.0.1 with all default settings. I've read
that a thread per index is used, that would mean I'm using 24 bulk threads
at one time. Am I right? if so, why I'm getting this rejection since queue
capacity is 50? It's possible that replicas consume threads as well? or a
thread per shard is used? this is my _cluster/health:

{
"cluster_name": "elasticsearch",
"status": "yellow",
"timed_out": false,
"number_of_nodes": 1,
"number_of_data_nodes": 1,
"active_primary_shards": 120,
"active_shards": 120,
"relocating_shards": 0,
"initializing_shards": 0,
"unassigned_shards": 120
}

120 shards = 24 indices * 5 shard

I've tried splitting the bulk indexing in different chunk sizes with same
result (as far as i understand this is not the solution).

Am I doing something wrong or I just have to increase the queue size?

I will appreciate any help

thanks

Threads are pooled, they are not used per index.

The queue length of 50 works in almost any case. 50 is also safe to protect
a node before being overwhelmed by too many documents. If not, think about
the bulk request size, and if your cluster is powerful enough for
processing the transmitted documents. You can add 1000-10000 requests in a
single bulk request.

If you still exhaust the bulk queue size, you should examine your code if
you really examine the bulk responses of each bulk request, and if your
bulk client limits the concurrency of bulk requests. Look at the
BulkProcessor source code to learn about concurrent bulk requests.

I understand, but I must be missing something.

5k documents * 24 indices = 120k requests, How am i supposed to bulk index
them? I've tried to set "index.refresh_interval" to "-1" to speed up the
process but still same result. splitting the bulk in different sizes didn't
work either.

Without being able to look at source code, it is difficult if not
impossible to find issues.

"index.refresh_interval: -1" must be set to the respective index,
preferably using the cluster update API (conf file or index creation
settings is also possible but not a good place for temporary settings). It
does not "speed up" bulk indexing, it saves some resources, the node does
not refresh that often for index reads, which is often a heavy operation.
With only 120k docs, distributed over 24 indices, the effect may not be
visible at all. Default flush buffer size for an index is 64k IIRC.

This is what I'm doing:

for each 24 locales:
POST /current_contenidos_[LOCALE] # creates index
PUT /current_contenidos_es_es/_settings # sets refresh_interval = -1

POST /_bulk HTTP/1.1" 200 2386284 (12 times [mixed requests for 24 indices])

for each 24 locales:
PUT /contenidos_es_es/_settings # sets back refresh_interval = 1s

So you use plain HTTP API? Do you evaluate the responses from POST /_bulk
requests before sending next request?

I'm using python, I just sent the log so you could figure out what I'm
doing.

I'm not evaluating the bulk response but logging them so I can see the
'rejected execution' error in most of them.

The queue length of 50 works in almost any case. 50 is also safe to
protect a node before being overwhelmed by too many documents. If not,
think about the bulk request size, and if your cluster is powerful enough
for processing the transmitted documents. You can add 1000-10000 requests
in a single bulk request.

If you still exhaust the bulk queue size, you should examine your code
if you really examine the bulk responses of each bulk request, and if your
bulk client limits the concurrency of bulk requests. Look at the
BulkProcessor source code to learn about concurrent bulk requests.

Hello,

I'm facing a problem bulk indexing 5k documents in 24 different
indices (i18n). I'm using elasticsearch 1.0.1 with all default settings.
I've read that a thread per index is used, that would mean I'm using 24
bulk threads at one time. Am I right? if so, why I'm getting this rejection
since queue capacity is 50? It's possible that replicas consume threads as
well? or a thread per shard is used? this is my _cluster/health:

{
"cluster_name": "elasticsearch",
"status": "yellow",
"timed_out": false,
"number_of_nodes": 1,
"number_of_data_nodes": 1,
"active_primary_shards": 120,
"active_shards": 120,
"relocating_shards": 0,
"initializing_shards": 0,
"unassigned_shards": 120
}

120 shards = 24 indices * 5 shard

I've tried splitting the bulk indexing in different chunk sizes with
same result (as far as i understand this is not the solution).

Am I doing something wrong or I just have to increase the queue size?

I will appreciate any help

thanks

Logging is not enough, you should care for the number of active requests
sent and the bulk request responses that came back. So you can control the
number of concurrent bulk requests that are active at a time, and if you do
so, you can limit this number, before exceeding the bulk queue size of 50.

Ok, I'm gonna play with that, but it seems too complicated just for bulk
indexing taking into account the low number of documents

Probably you should check why your cluster is yellow - is that a single
node only?

Bulk indexing with a green cluster should work flawlessly.

does not "speed up" bulk indexing, it saves some resources, the node does
not refresh that often for index reads, which is often a heavy operation.
With only 120k docs, distributed over 24 indices, the effect may not be
visible at all. Default flush buffer size for an index is 64k IIRC.

I understand, but I must be missing something.

5k documents * 24 indices = 120k requests, How am i supposed to
bulk index them? I've tried to set "index.refresh_interval" to "-1" to
speed up the process but still same result. splitting the bulk in different
sizes didn't work either.

Threads are pooled, they are not used per index.

The queue length of 50 works in almost any case. 50 is also safe to
protect a node before being overwhelmed by too many documents. If not,
think about the bulk request size, and if your cluster is powerful enough
for processing the transmitted documents. You can add 1000-10000 requests
in a single bulk request.

If you still exhaust the bulk queue size, you should examine your
code if you really examine the bulk responses of each bulk request, and if
your bulk client limits the concurrency of bulk requests. Look at the
BulkProcessor source code to learn about concurrent bulk requests.

Hello,

I'm facing a problem bulk indexing 5k documents in 24 different
indices (i18n). I'm using elasticsearch 1.0.1 with all default settings.
I've read that a thread per index is used, that would mean I'm using 24
bulk threads at one time. Am I right? if so, why I'm getting this rejection
since queue capacity is 50? It's possible that replicas consume threads as
well? or a thread per shard is used? this is my _cluster/health:

{
"cluster_name": "elasticsearch",
"status": "yellow",
"timed_out": false,
"number_of_nodes": 1,
"number_of_data_nodes": 1,
"active_primary_shards": 120,
"active_shards": 120,
"relocating_shards": 0,
"initializing_shards": 0,
"unassigned_shards": 120
}

120 shards = 24 indices * 5 shard

I've tried splitting the bulk indexing in different chunk sizes
with same result (as far as i understand this is not the solution).

Am I doing something wrong or I just have to increase the queue
size?

I will appreciate any help

thanks

Going green worked for 1 shard and 0 replicas, but dind't work for 5 shards
and 0 replicas being green.

Thanks

Probably you should check why your cluster is yellow - is that a single
node only?

Bulk indexing with a green cluster should work flawlessly.

Logging is not enough, you should care for the number of active requests
sent and the bulk request responses that came back. So you can control the
number of concurrent bulk requests that are active at a time, and if you do
so, you can limit this number, before exceeding the bulk queue size of 50.
