isolation level of put and scan

hi,experts: i have two concurrent threads to read/write same the same htable row. this row has two columns A and B. Currently this rows value is (A:a1, B:b1) thread 1 wants to read the value of this row's column value for A, B and thread 2 wants to update this row to (A:a2, B:b2) if thread 1,2

Re: isolation level of put and scan

i found a good article https://blogs.apache.org/hbase/entry/apache_hbase_internals_locking_and which seems to have answered my question. so the my described scenario will NEVER happen no matter whether A and B are in same column family? please kindly confirm thanks On Tue, Nov 17, 2015 at 4:07

Re: isolation level of put and scan

Oh, it will never happen. Each put will acquire row lock to guarantee consistency. 2015-11-17 16:20 GMT+08:00 hongbin ma : > i found a good article > https://blogs.apache.org/hbase/entry/apache_hbase_internals_locking_and > which seems to have answered my question. > > so
