Looks like the data is not getting evicted from the Ignite cache in spite of the expiration time set into the configuration. I notice that this issue happens when I use SQL to insert data into the cache table.
emplCache.query(new SqlFieldsQuery(
"CREATE TABLE Employee (id LONG PRIMARY KEY, firstName VARCHAR, lastName VARCHAR,
salary DECIMAL, gender VARCHAR)")).getAll();
SqlFieldsQuery insertqry = new SqlFieldsQuery("INSERT INTO Employee (id, firstName,
lastName, salary, gender) values (?, ?, ?, ?, ?)");
emplCache.query(insertqry.setArgs(Long.toString(count), words[1], words[2],
words[3], words[4])).getAll();
This was how I configured the expiry :
CacheConfiguration<?, ?> cfg = new CacheConfiguration<>(cacheName);
cfg.setCacheMode(CacheMode.PARTITIONED);
cfg.setName(cacheName);
cfg.setSqlSchema("PUBLIC");
cfg.setAtomicityMode(CacheAtomicityMode.ATOMIC);
cfg.setExpiryPolicyFactory(CreatedExpiryPolicy.factoryOf(new Duration(SECONDS, 1)));
However, I do not see this issue if I use the dataStreamer to insert the data.
IgniteDataStreamer<Integer, Employee> stmr = ignite.dataStreamer(cfg.getName())
stmr.addData(id, emp);
Have I missed some configuration setting?
[PS] Tried the following after Evgenii's answer:
// This is a util method that returns a cache config for the given cache name and the expiry time in seconds
CacheConfiguration<?, ?> cfg = CacheConfig.getCacheConfig("emplCache", 1);
IgniteCache<?, ?> emplCache = ignite.getOrCreateCache(cfg);
emplCache.query(new SqlFieldsQuery(
"CREATE TABLE Employee (id LONG PRIMARY KEY, firstName VARCHAR, lastName VARCHAR, salary DECIMAL, gender VARCHAR)"
+ "WITH \"template=emplCache\" ")).getAll();
Now i get this exception that the cache doesn't exist. But I am trying to create the table after creating the cache:

Table Employee will be created in another cache(that will be creted for it), thats why configured ExpiryPolicy will not be used.
To configure this new cache add "WITH \"template=CACHE_NAME\""
where CACHE_NAME is name of cache(or template) in your configuration. In your case it's cacheName;
For example, change your creation script to:
emplCache.query(new SqlFieldsQuery(
"CREATE TABLE Employee (id LONG PRIMARY KEY, firstName VARCHAR, lastName VARCHAR, salary DECIMAL, gender VARCHAR) " +
"WITH \"template=employee\" ")).getAll();
Here are link to doc
If you configure cache from java, you will need to add this cache with name emplCache to Ignite with:
ignite.addCacheConfiguration(cfg);
