-----------------------------------------
Summary: Unstable database sizes and update_seq values
Key: COUCHDB-2406
URL: https://issues.apache.org/jira/browse/COUCHDB-2406
Project: CouchDB
Issue Type: Bug
Security Level: public (Regular issues)
Components: Database Core
Reporter: Alexander Shorin
Each time requesting database info CouchDB 2.0 return different information
about database sizes and update seq while there is no any activity for
monitored database.
Script to reproduce:
{code}
import requests
import time
dburl = 'http://localhost:15984/test'
init_dbinfo = requests.get(dburl).json()
diff_found = False
while True:
dbinfo = requests.get(dburl).json()
for key, value in sorted(dbinfo.items()):
if dbinfo[key] != init_dbinfo[key]:
diff_found = True
print(key)
print('was:', init_dbinfo[key])
print('now:', dbinfo[key])
print('-' * 20)
if diff_found:
break
time.sleep(1)
{code}
Example output:
{code}
data_size
was: 25807939
now: 25808590

disk_size
was: 71333328
