Is there any limit on size of metric whose data type is string in sonarqube?
4000 characters is the max size of data measures

I'm noticing if I sum up the _size property of all my ElasticSearch documents in an index, I get a value of about 180 GB, but if I go to the _stats API endpoint for the same index I get a size_in_bytes value for all primaries to be 100 GB.
From my understanding the _size property should be the size of the _source field and the index currently stores the _source field, so should it not be at least as large as the sum of the _size?
The _size seems to be storing the actual size the source document. When actually storing the source in stored_fields, Elasticsearch would be compressing it(LZ4 default if I remember correctly). So I would expect it to be less size on disk than the actual size. And if the source doesn't have any binary data in it, the compression ratio is going to be significantly higher too.
Will the size of the elastic search index decrease (and performance
increase due to reduce memory footprint) if I were to shorten field
names?
Fields names are stored in the field info file, with suffix .fnm
FieldName is just a UTF-8 string there.
You could estimate the current size of it and make any assumptions about how much it would save you space, but I’m pretty much sure, that it will be negligible, so there is very little sense in optimizing field names.
For example, my tiny playground index of the size 500 Mb with around 100-150 fields have total size of all field info files to be 188 kB which makes it 0.04% out of total size.
I'm newbie on Oracle and I want to know the following limitations on Oracle 12 :
Maximum Database Size
Maximum Table Size
Maximum Row Size
Maximum Rows per Table
Maximum Columns per Table
Maximum Indexes per Table
Currently I found these limitations
Maximum Database Size = 8000T
Maximum Table Size
Maximum Row Size
Maximum Rows per Table = Unlimited
Maximum Columns per Table = 1000
Maximum Indexes per Table = Unlimited
Thank you for your help
All this information is in the docs:
Physical limits:
https://docs.oracle.com/database/121/REFRN/GUID-939CB455-783E-458A-A2E8-81172B990FE9.htm
Logical limits:
https://docs.oracle.com/database/122/REFRN/logical-database-limits.htm
Maximum row size:
For Oracle8, Release 8.0 and later, the answer is 4,000GB (or 4GB per
LOB, 1,000 LOBs per table). Just take the maximum varchar2 size (4000)
or char size (2000) and add them up—4000x1000=4,000,000 bytes of
structured data.
I can't submit this question with just a title. Is it possible to get the total size in bytes of all documents in an Elasticsearch type?
I have a bunch of rows on HBase which store varying sizes of data (0.5 MB to 120 MB). When the scanner cache is set to say 100, the response sometimes gets too large and the region server dies. I tried but couldn't find a solution. Can someone help me finding
What is the maximum response size that HBase supports?
Is there a way to limit the response size at the server so that the result will be limited to a particular value (answer to the first question) so that the result will be returned as soon as the limit is reached?
What happens if a single record exceeds this limit? There should be a way to increase it but I don't know how.
1. What is the maximum response size that HBase supports?
It is Long.MAX_VALUE and represented by the constant DEFAULT_HBASE_CLIENT_SCANNER_MAX_RESULT_SIZE
public static long DEFAULT_HBASE_CLIENT_SCANNER_MAX_RESULT_SIZE = Long.MAX_VALUE;
2. Is there a way to limit the response size at the server so that the result will be limited to a particular value (answer to the first question) so that the result will be returned as soon as the limit is reached?
You could make use of the property hbase.client.scanner.max.result.size to handle this. It allows us to set a maximum size rather than count of rows on what a scanner gets in one go. It is actually the maximum number of bytes returned when calling a scanner's next method.
3. What happens if a single record exceeds this limit? There should be a way to increase it but I don't know how.
Complete record(row) will be returned even if it exceeds the limit.
