I have started working with Cassandra database recently and I was trying to insert some data into one of my column family that I have created. Below is the code by which I am trying to insert into Cassandra database.In my case I have around 20 columns in my column family so that means I need to add below linemutator.newColumn(Column Name, Column Value);Twenty times in my below code which looks ugly to me. Is there any way, I can simplify the below method either by using reflection or some other way so that If I have more than 20  columns, I should not keep on adding extra line in my below code.for (int userId = id; userId < id + noOfTasks; userId++) {    Mutator mutator = Pelops.createMutator(thrift_connection_pool);    mutator.writeColumns(column_family, String.valueOf(userId),            mutator.newColumnList(            mutator.newColumn(a_account, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_advertising, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_avg_selling_price_main_cats, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_cat_and_keyword_rules, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_csa_categories_purchased, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_customer_service, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_demographic, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_favorite_searches, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_favorite_sellers, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}),             mutator.newColumn(a_financial, {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109})            mutator.newColumn(some othe column, its value)            .....            .....            .....            ));    mutator.execute(ConsistencyLevel.ONE);}Any help in simplifying the above method will be of great help to me. I was thinking of using a Constant class file like below which will have below methods for each column:public static void setAccount_epu(final Mutator mutator, final int userId) throws SQLException {    final String A_ACCOUNT = {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109};    mutator.newColumn(a_account, A_ACCOUNT);}public static void setAdvertising_epu(final Mutator mutator, final int userId) throws SQLException {    final String A_ADVERTISING = {\lv\:[{\v\:{\thirdPartyAdsOnEbay\:null,\ebayAdsOnThirdParty\:null,\userId\: + userId + },\cn\:2}],\lmd\:20130206211109};    mutator.newColumn(a_advertising, A_ADVERTISING);}public static void setClv_info_epu(final Mutator mutator, final int userId) throws SQLException {    final String A_CLV_INFO = {\lv\:[{\v\:{\tenureSiteReg\:null,\bghtItms\:48,\pnlValue\:105.478409,\byrSgmnt\:2,\cstmrId\:\814296998\,\slrRevRnk\:-99.0,\soldItms\:0,\slrSgmnt\:6,\byrRevRnk\:0.013,\mainAcct\:78,\gmv\:0.0,\cstmrRevRnk\:0.021,\pnlRev\:313.438843,\cstmrSgmnt\:51,\gmb\:4674.76,\totalVal\:142.536293,\userId\: + userId + },\cn\:42}],\lmd\:20130206212543};    mutator.newColumn(a_clv_info, A_CLV_INFO);}public static void setClv_behavior_epu(final Mutator mutator, final int userId) throws SQLException {    final String A_CLV_BEHAVIOR = {\lv\:[{\v\:{\behaviorInfo\:\111:0.56,113:0.33,116:0.10,118:0.03,117:0.00,69:0.00,73:0.00,115:0.00,108:0.00\,\usrId\:1001116884,\userId\: + userId + },\cn\:41}],\lmd\:20130206212543};    mutator.newColumn(a_clv_behavior, A_CLV_BEHAVIOR);}public static void setClv_churn_epu(final Mutator mutator, final int userId) throws SQLException {    final String A_CLV_CHURN = {\lv\:[{\v\:{\churnPrdctvDecileNum\:9,\churnPrdctvScoreVal\:671.38116,\userId\: + userId + },\cn\:44}],\lmd\:20130206212543};    mutator.newColumn(a_clv_churn, A_CLV_CHURN);}Can I then use some reflection around that?
Inserting data into column family
java;cassandra
It looks like the pattern is alway the same, I am right? Then you could just do:String commonColumnValue = {\lv\:[{\v\:{\regSiteId\:null,\userState\:null,\userId\: + userId + },\cn\:1}],\lmd\:20130206211109}String[] columns = {a_account, a_advertising, ..., a_financial} //extend by your needsfor(String columnsItem : columns)    mutator.newColumn(columnsItem, commonColumnValue);
