JdbcStringBasedCacheStore loads previous data from store before an insert
-------------------------------------------------------------------------
Key: ISPN-686
URL: https://jira.jboss.org/browse/ISPN-686
Project: Infinispan
Issue Type: Bug
Components: Loaders and Stores
Affects Versions: 4.2.0.ALPHA2, 4.1.0.Final, 4.0.0.Final
Reporter: Sanne Grinovero
Assignee: Manik Surtani
Fix For: 4.2.0.Final, 5.0.0.Final
The JdbcStringBasedCacheStore implementation loads the previous data on an insert to find
out if it should generate an UPDATE or INSERT statement, while it would perform much
better to just verify if the primary key exists.
On top of this, some databases provide ways to avoid the need to check at all, like
MySQL's " INSERT ... ON DUPLICATE KEY UPDATE"

Sanne Grinovero commented on ISPN-686:
--------------------------------------
Instead of using "ON DUPLICATE KEY UPDATE" I'm now using MySQL's other
proprietary extension: "REPLACE". In case people wished to use MyISAM engine,
they could even use "REPLACE DELAYED" which seems to nicely fit the requirements
for this.
To use these I had to implement a new custom CacheStore extending
JdbcStringBasedCacheStore; I could contribute this if there's interest, but I think
there would be more value in fixing the existing JdbcStringBasedCacheStore and letting
users override the full SQL statement, or plug this logic in the existing database
autodetect: I guess other RDBMS could have similar tricks to use.

Trustin Lee commented on ISPN-686:
----------------------------------
Infinispan already has an abstraction called TableManipulation which is basically a
factory of SQL strings. I think we can add TableManipulation.getInsertOrUpdateRowSql().
The default implementation could return null (i.e. no proprietary extension), and a user
could override it.
Another possible optimization is to attempt an UPDATE first instead of SELECT. If the
number of updated rows is 0, we can execute an INSERT. Assuming UPDATE is more common
than INSERT, we save one statement.
WDYT? (Just making sure because I'm not sure I'm so familiar with the codebase
yet :)

--------------------------------------
+1 for the new tablemanipulation method.
I won't assume update is more common, in the case of the LuceneDirectory it's
extremely unlikely, it's picking a new key for each write; (that's why I'm
attempting to avoid the return value at all costs, totally pointless).
Assuming we go for the UPDATE + INSERT strategy, is there a lock on the key held to
protect from a race condition?

Affects Versions: 4.0.0.Final, 4.1.0.Final
Reporter: Sanne Grinovero
Assignee: Tristan Tarrant
Fix For: 5.2.0.FINAL
The JdbcStringBasedCacheStore implementation loads the previous data on an insert to find
out if it should generate an UPDATE or INSERT statement, while it would perform much
better to just verify if the primary key exists.
On top of this, some databases provide ways to avoid the need to check at all, like
MySQL's " INSERT ... ON DUPLICATE KEY UPDATE"

I took this one, since I need a optimization shortly. My simple approach is just execute
Select ID w/o unmarshall maybe existing stuff to decide of insert/update should be used.

Hi Thomas,
"select ID" looks like a good compromise, but which DB are you using? As I
mentioned above (years ago!) MySQL is able to deal with it in a single statement; Back in
that time I was an external contributor, but shared my custom implementation using MySQL
as a patch - should be in the mailing lists archive, but worth looking for only if you
intend to MySQL.
I'm glad that someone finally volunteers on this :)

The mentioned sultion with "select ... for update" in a transaction makes in
this case no sense, because this would only affect of the entry exists. So the risk with
"SQLIntegrityConstraintViolationExceptions." still exists with this generic
solution. Luckily I did not run anymore in this exception under load ;-)

Sanne Grinovero commented on ISPN-686:
--------------------------------------
I wonder if the race condition is really possible with a write-through configuration: in
theory the writing node owns a lock on the written entry.
I guess it's more tricky for async cacheloader: it's unlikely because of the
de-duplication of writes on the same key, but still possible.
Yes for Oracle you need a stored procedure to implement it properly, but what's wrong
with suggesting & documenting that? Especially as many other databases do have a
solution, like UPSERT or MERGE.
I don't like the Transactions approach as it could interfere with other transactions
integration; this doesn't look like the proper layer to manage transactions.
