The method for processing poultry data by using the caching technology of the invention is implemented by the following steps.
1. Correlating batches of poultry
Acquiring all the batches to be calculated in the system, wherein the batches to be calculated are the batches of which the number of days from the incubation date to the current date (the date calculated by the task) of each batch is less than the maximum number of days set by the system (the current system is set to 1000, and can be adjusted according to actual business requirements), associating each batch with all the batches of the same strain generation by a key value pair, and caching the batches into an internal memory.
For example, if the calculated batch is Y31701, and the batches of the same line and generation have Y31701 and Y31702, then Y31701 is used as a key, and Y31701 and Y31702 are stored as values in association with each other, and json format data is stored: { "Y31701" [ "Y31701", "Y31702" ] }
Line, generation and batch meanings:
the strain is directly related to the variety of poultry, such as Y1 variety, Y2 variety, K1 variety, K2 variety and the like;
generation: it means how many times the poultry has been hatched, for example: the generation of a batch of chickens is 1, then the generation of the next generation of the batch of chickens is 2;
batch: hatching of the next generation is carried out in several batches, for example: one batch was hatched in january, batch number 01, and then one more batch was hatched in february, batch number 02.
The cock of the same strain and the same generation corresponding to the related batch can be paired with a plurality of hens, and all the chickens hatched by the plurality of hens in the same day of the same month belong to the same batch.
2. Data acquisition
And acquiring the identity information data of each batch from the database, and acquiring the original property data of each batch.
The identity information data and the original property data are both used for calculating index data service, and before the index data is calculated by using the original property data, an index information attribute set of the whole batch needs to be known.
1. The set of indicator information attributes includes:
index ID: the index data acquisition module is used for describing index data obtained by calculation, and each index data corresponds to an index ID; as shown in table 1 below, the source trait relates to the eggshell strength, ESS represents the eggshell strength, and the eggshell strength of 64 weeks old, 66 weeks old, 68 weeks old and the like of each chicken needs to be calculated, and then the index ID corresponding to the eggshell strength is expressed as: ESS64, ESS66, ESS68, etc.;
and (3) index description: an index for describing the required calculation;
source characters: determining which property index data needs to be obtained; as shown in table 1, the index data of eggshell strength required to be obtained is determined by the source character ID and the source character description together;
source sex: including a cock and a hen, which means that only the trait data of poultry of this sex is obtained to calculate index data;
the calculation logic: a method for determining index data derived from raw trait data;
starting and ending day ages: the system is used for determining the starting age and the ending age of the original property data required to be acquired for calculating the current index ID;
calculation of age of day is started: indicating that index data are obtained by calculation according to original character data only when the age of the poultry is larger than the age of the poultry, and if the age of the batch is smaller than the age of the poultry, the index data of the batch are not calculated temporarily; taking the following table 1 as an example, if the strength of the eggshell of a chicken at the age of 64 weeks needs to be calculated, the chicken needs to wait for being bred to the age of 450 days and then calculate;
the calculation type is as follows: including individuals, half-siblings, full-siblings and parents, for describing whether the index data currently calculated is index data of the poultry itself or index data of the half-siblings, full-siblings or parents thereof.
Some basic concepts:
the age in days: the day-old of the hatched chickens is 1 day-old, and the day-old of the hatched chickens is 1 day-old, wherein 1 day-old is added every time;
individual: the method comprises the steps of (1) indicating the chicken, wherein the individual calculation type refers to the calculation of relevant indexes of the chicken;
half siblings: all children of the same chicken as the father are half siblings, and the half sibling calculation type refers to the calculation of related indexes of brothers and sisters of the same chicken and the father and the alien mother;
full sibling: all children of the parent and the father are the same chicken are the same siblings, and the calculation type of the same siblings refers to the calculation of related indexes of brothers and sisters of the same chicken and the same father and mother;
parent strain: the mother of the chicken, the parent calculation type refers to the correlation index of the mother of the chicken.
Table 1 illustrates the eggshell strength index information attribute set of the present invention.
Table 1: poultry eggshell strength index information attribute set
In table 1, "range from" and "range to" respectively indicate which day-old section the property data needs to be acquired in order to calculate the corresponding index, and in the first row, in order to calculate the eggshell strength of 64 weeks, the eggshell strength between 442 days old and 448 days old needs to be acquired.
2. Raw trait data
The original character data comprises a measuring date, a character index and a character value;
the character indexes correspond to the source characters in the index information attribute set and are used for determining which character data the measured character data belong to; the measuring date is used for determining the day age of the poultry corresponding to the currently measured character data.
The day age and the week age corresponding to the current date can be obtained by measuring the date and the incubation date, wherein the day age = the measuring date-the incubation date +1.
3. Identity information data
The identity information data comprises the identity numbers of the poultry, the belonging batch, the identity numbers of the father and the mother, and the index information attribute set of each poultry corresponds to the original property data of the poultry through the identity numbers. The identity number of each chicken is unique and consists of strain + generation + batch + wing number.
Table 2: raw character data and identity information data of eggshell strength of poultry
Relation between index information attribute set and original character data: the data in the index information attribute set describes which type of index data needs to be acquired, so that based on the records in the index information attribute set, it can be known which original property data needs to be acquired in order to obtain the corresponding index data.
For example, in the first row of table 1, the 64-week-old eggshell strength of an individual needs to be obtained, and at this time, the eggshell data values of the individual from 442 days old to 448 days old are obtained from the original property data, and then the 64-week-old eggshell strength of the individual can be calculated. The specific computational logic is described in detail below.
In the invention, the index information attribute set and the original character data also comprise ID numbers of father and mother of the poultry, and the original character data of the half sibling, the half sibling or the parent of the poultry is obtained through the ID numbers of the father and the mother, so that the index data of the poultry can be conveniently obtained through the original character data of the half sibling, the full sibling and the parent, and the index data of the half sibling, the full sibling and the parent of the corresponding individual can be further calculated.
3. Caching of data
When index data of a batch is calculated, first, associated batch data of the batch is acquired from a cache (stored in the cache in step 1), for example: when the current calculation batch is Y71301, the associated batches are Y71301 and Y71302, all the identity information data of the associated batches are taken out of the database and cached in the memory, namely the identity information data of the Y71301 batch is put into the cache, the identity information data of the Y71302 batch is put into the cache, when the Y71302 batch is calculated, the associated batches are still Y71301 and Y71302, and at this time, the identity information data are not required to be obtained from the database and then put into the cache, because the identity information data are already put into the cache when the Y71301 batch is calculated.
Similarly, all original property data of related batches are taken out from the database, grouped according to properties, and cached in a memory (for example, all original property data of the property of ESS-eggshell strength, all original property data of the property of EST-eggshell thickness, and cached in the memory), for example: and if the current calculation batch is Y71301, the associated batches are Y71301 and Y71302, caching all original property data in the associated batches in a memory from the database, namely putting the property data of the Y71301 batch into the cache and putting the property data of the Y71302 batch into the cache, and when the Y71302 batch is calculated, the associated batches are still Y71301 and Y71302, and at this time, the property data do not need to be acquired from the database and then put into the cache because the property data are already put into the cache when the Y71301 batch is calculated.
4. Calculation of index data
And circularly calculating the index data of all the chickens in the batch of each index, acquiring all the batches to be calculated from the database during calculation, and then transmitting the index information data set serving as a parameter to a method for calculating the index data of one batch. The calculation processes are different according to different types of indexes, and the following calculation processes are respectively explained according to the types of the indexes:
1. calculation of individual type index data
(1) Acquiring all identity information data of the batch from a cache;
(2) All the original trait data of all the chickens of this batch are obtained from the cache by traits, such as: when an ESS36 (36-week-old eggshell strength) index of a Y71301 batch is calculated, original property data of the ESS (source property of the ESS 36) of the Y71301 batch is required to be acquired;
(3) Circularly calculating the index data of the index of each chicken in the batch, acquiring the original character data of the chicken measured from the beginning age to the ending age of the index, and calculating the index data according to the calculation mode;
(4) After the index calculation of one chicken is completed, the index data are not directly inserted into the database and are firstly stored in the memory, and after the index data of all the chickens in the batch are calculated, the index data are inserted into the database at one time, so that the times of accessing the database are reduced. The database pressure is reduced.
2. Calculation of semi-sibling or full sibling type index data
(1) Acquiring all chicken data of the batch from a cache, and acquiring all chicken data of a related batch besides acquiring all chicken data of the batch;
(2) Acquiring all original character data of all chickens of the batch from the cache through characters, acquiring all original character data of the index of the batch in addition to acquiring the original character data of the index of the batch, for example: when calculating the ESS36 (36 week-old eggshell strength) index for the Y71301 lot, raw property data for the ESS properties of the Y71301 and Y71302 lots need to be obtained.
(3) Circularly calculating the index data of the index of each chicken in the batch, if the index data is half sibling, firstly acquiring the hens in all children of the same father as the chicken from all the chicken data of the associated batch, if the index data is full sibling, firstly acquiring the hens in all children of the same mother as the chicken from all the chicken data of the associated batch, then acquiring the character (source character of the index) data of the hens measured from the beginning age to the ending age of the index, and calculating the index data according to the calculation mode;
(4) After the index calculation of one chicken is completed, the index data are not directly inserted into the database and are firstly stored in the memory, and after the index data of all the chickens in the batch are calculated, the index data are inserted into the database at one time, so that the times of accessing the database are reduced. The database is relieved of pressure.
3. The calculation method is as follows:
and (4) cumulative calculation: the value of the index is obtained after the value of the property data is accumulated;
and (3) assignment calculation: the trait value of the first piece of trait data is the value of the indicator (if the indicator is an assignment calculation, there is only one item of trait data during this period); for example, if the strength of the 64-week-old eggshell is required to be calculated, the strength of the eggshell is measured only once during the period from 442-448 days old, and the only eggshell strength is taken as the strength of the 64-week-old eggshell.
And (3) calculating an average value: the value after the value of the character data is averaged is the value of the index;
and (3) calculating standard deviation: the value after the standard deviation of the value of the trait data is the value of the index.
Table 3 illustrates eggshell strength index data of the present invention.
Table 3: index data of eggshell strength of poultry
Relationship between index data and original property data: the index ESS36-36 weeks old eggshell strength, the calculation mode of the index is average value calculation, starting day age-246 and ending day age-254, and the calculation method comprises the following steps: measurements of traits (the source trait of the index) between 246 and 254 days of age are taken and averaged, which is the value of this index for ESS 36.
5. And after the index data of all batches are calculated and are all inserted into the database, all the data in the cache are cleared.
Tables 4 and 5 below show the data processing efficiency corresponding to the existing data processing method and the processing method of the present invention, respectively, and it can be seen from the comparison of tables 4 and 5 that the improved processing algorithm of the present invention can greatly increase the calculation speed.
Table 4: calculated speed of existing poultry data processing method
Table 5: processing speed of the poultry data processing method of the invention
In conclusion, the index data processing algorithm realized by combining the caching technology and the multithreading technology greatly improves the calculation speed. The calculation speed can be obviously improved as long as the hardware configuration of the calculation server is improved, but the existing processing algorithm is limited in the database, and the improvement of the configuration of the database service cannot obviously improve the calculation speed.
